Note
If you are working on the CNC Mill 2 - Trak upgrade please read the CNC Mill 2 Lab Instructions.
Before using the machine fully read and understand the material covered in this guide. This guide is not a replacement to the full documentation provided by Southwestern Industries, Inc. If you have any questions please ask one of the staff.
Overview
The Trak DPM SX2 is intended for medium sized work. The machine's X, Y, Z limits are 32" x 16" x 27" (812.8mm x 406.4mm x 685.8mm) and the table size is 49" x 9" (1244.6mm x 228.6mm). The machine has a spindle speed range of 300 to 5000 RPM with a maximum feed rate of 90 IPM (2286 mm/m) in the X,Y & Z axis. If you need a machine that is capable of handling larger work consider the HAAS VM2 (capable of doing 5-axis work).
Front Control Panel
The front control panel is where a number of important machine controls are located. This includes the Go/Stop buttons, emergency stop, computer on/off, 2- 3-axis selection and a number of spindle controls. You should familiarize yourself with these controls and their location.
Reference Tool and Tool Setter
The reference tool, used with a tool setter, is used to set the tool setting reference position.
Tool Setter
The tool setter is used to set the reference tool and all cutting tool heights.
Tool Holders
The Trak DPM SX2 uses a tool holding system called R8 collets. They can be a collapsible collet, or a solid style built into the cutter.

Axis Selection
Warning
Make sure you are in 3 axis mode when machining a CAM program. Use the 2 axis mode when conversationally programming at the machine.
To switch between 2 & 3 axis modes, press the soft key labeled "SYS" located on the far left side of the pendant. It doens't look like a button, just the letters SYS.
This will bring up the screen where you will be able to choose between 2 and 3 axis modes of operation on the DPM2.
To escape this screen, press "MODE" and "DRO".
If you look at the top of the screen while in "DRO", you will be able to see if you are in 2 axis or 3 axis mode of operation.
Basic Machine Operation
JOG
You can move the table and head manually, if desired. Press JOG, and that activates the handles to move the table.
A flashing message will appear saying "CAUTION: JOG KEYS ARE ACTIVE".
To jog, press the X, Y or Z hard keys. To stop jogging, release the key.
The speed of jog is displayed in the box next to the words "Feed Rate” on the lower left side of the LCD screen.
Press the +/- hard key to reverse direction. When the number in the Feed rate box is negative, this indicates the minus direction.
Press the FEED RATE keys to reduce and to increase the jog speed in 10 percent increments. The changes in speed may be seen in the Feed Rate box and on the green feed rate indicator. The amount of override is displayed in the Override box.
To jog at a certain rate, simply enter that number as inches or mm per minute and then press the X, Y or Z key. You may also use the override key to adjust this number.
Press RESTORE to return to 150 ipm or 3800mm/min.
To move the Z-axis, you need to jog it to within 3-4" of the top of the part. Use the quill handle to lower the tool to the desired height.
Power Feed
The servomotors can be used as a power feed for the table, saddle or quill, or all three simultaneously.
Press the POWER FEED soft key.
A message box will appear that shows the power feed dimensions. All power feed moves are entered as incremental moves from the current position to the next position.
Enter a position by pressing the axis key, the distance to go and the +/- key (if needed). Input the entry by pressing INC SET. For example, if you wanted to make a power feed move of 2.00" of the table in the negative direction, you would enter: X, 2, +/-, INC SET.
Initiate the power feed move by pressing GO. You must turn the spindle on. Use the RPM calculator to determine the correct RPM.
The feedrate is automatically set to 10 ipm (or 254 mm per min). Press FEED up or FEED down to adjust the feedrate from 1 ipm to 100 ipm. (or 25 to 2540 mmpm)
Press STOP to halt power feed. Press GO to resume.
Press RETURN soft key to return to DRO.
Do One
The Do One routines in the DRO mode allow you to do one CNC operation while machining manually without having to write a program.
The programming and tool path of the events in Do One are nearly identical to those in the Program Mode.
GO TO
The GO TO function in the DRO mode allows you to set a dimension in X, Y or Z at which you want the machine to stop moving when you are manually moving the machine. For example, if you wanted to machine manually from your current position to exactly 2" from the X zero, you would input: GO TO, X, 2, ABS SET. While the GO TO window is displayed, the ProtoTRAK SMX will not let you pass that 2" dimension you set.
Press the GO TO key.
Enter the axis, X, Y, Z or any combination. Input the dimension(s).
Press INC SET or ABS SET.
Crank the handwheel. Motion will stop at the entered dimension even if you continue to crank the handwheel.
Return to Absolute Zero
At any time during manual DRO operation you may automatically move the table to your absolute zero location in X and Y by pressing the RETURN ABS 0 soft key. When you do, the message window will read "Ready to Begin: Press Go when Ready”. Make sure your tool is clear and press the GO key. The servos will turn on, move the ram to Z retract then move the table at rapid speed to your X and Y absolute zero position, and then turn off. You will be at zero and in manual DRO operation.
When you are in 2-axis CNC operation, only the X and Y will move, the ram will not.
Spindle Operation
Spindle speeds are set and adjusted through the controller.
To set spindle speed press the SPIN SPEED softkey. The Data Input Line will prompt “Spindle RPM”. Enter the RPM value (40-600 in low, 300-5000 in high) and press SET. If the spindle was already on when you began to enter the new speed, it will stay at the current speed until you press the SET key.
You may override the spindle speeds with the OVERRIDE display hard key. Press the F / S key until the LED on the S (for Spindle) side is lit. Use the up and down arrow keys to change the spindle speed in 5% increments per button press.
Conversational Programming
Teach
Teach gives you the ability to enter X and Y dimensions into a program. It can be a useful way of entering a few manual moves for operations like clearing out excess material or remembering a few hole locations.
The process of using Teach is in two parts. The first part takes place in the DRO Mode. This is where you start the Teach program, establish the program events and enter the X and Y dimensions. The second part is in the Program Mode. This is where you complete the Teach events that you began in the DRO Mode by entering the rest of the data. Once the data is entered, the Teach events become just like the other events that make up a program.
Entering Teach Data
From the DRO screen, press Teach.
On the top of the screen, you will see the message "Teach" and an event counter. When you enter Teach, you are actually programming events. If there is already a program in current memory, Teaching will add events to the end of the program. If there is not already a program in current memory, Teaching will start a new program. For example, if you already had a program in current memory that had 10 events, when you press Teach, the event counter will say EVENT 11. If there was no program, the event counter will say EVENT 1. The event counter shows the event for which data is being entered. You may teach in position, drill and mill events only.
Make sure the tool is in the correct position before you press one of the soft keys!
On the first Teach screen, the softkeys are:
POSN
A position move. For two-axis programming, the POSN and DRILL events are combined.
DRILL
A drill or bore.
MILL BEGIN
The beginning of a straight line or MILL event.
END TEACH
Ends the teaching process and returns you to the main DRO screen.
If you press the POSN or DRILL key, the event counter will go up by one and the screen remains the same. If you press the MILL BEGIN key, the event counter stays on the same number. That is because you have given the beginning point of the line but not yet the end. The softkey selections will change to:
MILL END
The last point of the Mill event. Press this to end the Mill event and select a POSN, DRILL or new MILL event.
MILL CONT
The last point of the current Mill event, but the beginning of the next Mill event. You may enter successive Mill events by pressing the MILL CONT key.
Pressing either of the above softkeys will cause the event counter to increase by one.
At any time you may exit the Teach and return to the DRO screen. The events you have defined with their X and Y dimensions are finished in the Program Mode.
Finishing Teach Events
The Teach events that are started in the DRO Mode must be finished in the Program Mode before running. Teach events are of these different types:
TEACH POSN - for two-axis operation, the Position and Drill event types are combined.
TEACH DRILL- this may also be made into a bore event.
TEACH MILL - a straight line that specifies the beginning and the end. When TEACH MILL events are defined using the CONT MILL softkey, the prompts for information that cannot change will be suppressed.
When a Teach event is unfinished, the words NOT OK will appear next to the event type.
Once the prompts are completed, the words NOT OK and Teach will disappear. The event will become a normal MILL, DRILL, or POSN event.
Tool #
To change tools, press the TOOL # soft key and enter the tool number when prompted by the Data Input Line.
Program Events
Events are fully defined pieces of geometry. By programming events, you tell the ProtoTRAK SMX CNC what geometry you want to end up with; it figures the tool path for you from your answers to the prompts and the tool information you give it in the Set-Up Mode.
Press Mode, select the PROGRAM soft key.
The first screen you see is the Program Header Screen. Use up to a 5 digit number to name your program.
You do have the option to scale your geometry, from .1 to 10 times the programmed dimensions. Leave this at 1 for no change.
Do not change any of the other settings on this page.
Once you have named it, pres the GO TO BEGIN soft key to begin programming.
POSN
This event type positions the table and quill at a specified position. The positioning is always at rapid speed (modified by feedrate override) and in the most direct path possible from the previous location. The most common use of the position event is to move the tool around an obstacle such as a clamp. For this reason, Z and X - Y motion will not occur simultaneously. First, the Z (head) will move to the higher of the Z rapid position of the current and next event, then the X (table) and Y (saddle) will move at to the programmed position.
To program a Position event press the POSN soft key.
Prompts for the Position event:
X END is the X dimension to the position.
Y END is the Y dimension to the position.
Z Rapid is the Z dimension to the position.
RPM is the spindle RPM for the event. INC SET will use the RPM of the previous event.
Tool # is the tool number you assign. INC SET will use the tool number of the previous event.
DRILL
This event positions the table to the specified X and Y position, moves the HEAD at rapid to the Z RAPID location, feeds the quill to the Z END location, and rapids back to Z RAPID for drill, and feeds back for bore.
Press the DRILL soft key.

ARC
This event allows you to mill with circular contouring any arc (fraction of a circle) that lies in the XY plane or a vertical plane (see Section 5.3). Vertical plane arcs are also limited to those that are entirely concave or convex (in other words, if you think of the arc lying on the surface of the earth, then it can't cross the equator).
In ARC events when X Center, Y Center, and Z Center are programmed incrementally, they are referenced from X End, Y End, and Z End respectively. An ARC event may be programmed with a CONRAD if it is connective with the next event (this next event must lie in the same plane as the Arc event).
Note: When an arc is a 180 degree arc, there are several paths that all have the same beginning, ending, and center locations. To illustrate, imagine that if you were on the earth's equator and you wanted to get to the other side of the earth you could go clockwise or counterclockwise around the equator, or you could go up over the north pole, or down under the south pole.
The ProtoTRAK SMX CNC will automatically assume that all 180 degree arcs that have the same beginning, ending and center dimensions for Z, lie in the XY plane.

This event selection gives you a choice between, circle pocket, rectangular pocket and irregular pocket within the XY plane.
Pockets include machining the circumference, as well as all the material inside the circumference of the programmed shape. If a finished cut is programmed, it will be made at the completion of the final pass. The cutter will begin away from the wall to be finished, arc into the finish cut, arc out of the finish cut, and position itself the finish cut dimension away from the part before moving the tool out of the part.
The factory setting for tool stepover while machining a pocket is 70%. This may be changed. When you first enter the pocket event, the blue ? will appear next to the help key. Pressing Help will give you the choice of entering a new tool stepover percentage. The value you enter here will remain the same until you change it again.

Note – if you press the HELP key when you are on the X1 prompt, you can adjust the step over distance of the face mill. The default is 95% of the cutter width. You can adjust it from 1 to 99%.
Islands
Within the Pocket event choices, you may also select a circular, rectangular or irregular island. An island is a shape that is left standing when the surrounding material is removed. The ProtoTRAK gives you the ability to machine almost any shape as an island within a rectangular pocket. Both the shape of the island and the dimension of the surrounding pocket are defined within the island event.
The tool path for machining the island event is that the tool will first plunge or ramp into the material next to the island, offset by the programmed finish cut, to the depth of the first pass. The tool will machine the perimeter of the island, offset by the island finish cut. Then the tool will machine the material in the pocket in a spiral path, moving away from the island in the programmed clockwise or counterclockwise direction. It will continue this outward spiral motion until it encounters the programmed rectangular perimeter (or pocket). It will then follow the perimeter, offset by the pocket finish cut.
It will proceed in this manner through the number of programmed passes. On the final pass, it will machine the island finish cut, then the pocket finish cut. If a Z finish cut is programmed, it will do this in the same spiral pattern as the roughing passes between machining the island and pocket finish cuts. The tool will ramp away from the finish cut by the amount of the finish cut before it raises out of the part.

Tool #: is the tool you assign.
Subroutine Events
The Subroutine Events are used for manipulating previously programmed geometry within the XY plane. The Subroutine Event is divided into three options: Repeat, Mirror, and Rotate. Repeat and Rotate may be connective. As long as the rules of connectivity are satisfied, the ProtoTRAK SMX CNC will continue milling between preceding and subsequent events.
Press the SUBROUTINE (SUB) soft key to call up the Repeat, Mirror, and Rotate options.
REPEAT
Allows you to repeat an event or a group of events up to 99 times with an offset in X and/or Y and/or Z. This can be useful for drilling a series of evenly spaced holes, duplicating some machined shapes, or even repeating an entire program with an offset for a second fixture.
Repeat events may be "nested". That is, you can repeat a repeat event, of a repeat event, of some programmed event(s). One new tool number may be assigned for each Repeat Event.
Press the REPEAT soft key.
Where:
First Event #: is the event number of the first event to be repeated.
Last Event #: is the event number of the last event to be repeated; if only one event is to be repeated, the Last Event # is the same as the First Event #.
X Offset: is the incremental X offset from event to be repeated.
Y Offset: is the incremental Y offset from event to be repeated.
Z Offset: is the incremental Z offset from event to be repeated.
Z Rapid Offset: is the incremental Z rapid offset from event to be repeated.
# Repeats: is the number of times events are to be repeated up to 99.
% RPM: is the percentage of RPM in the programmed events. SET will load in the assumed % of 100%.
% Feed: the percentage of the feeds programmed in the repeated events. 100% is assumed.
Tool #: is the tool number you assign.
MIRROR
Is used for parts that have symmetrical patterns or mirror image patterns. In addition to specifying the events to be repeated, you must also indicate the axis or axes (X or Y or XY are allowed) that the reflection is mirrored across. In addition, you must specify the offset from absolute zero to the line of reflection. You may not mirror another mirror event, or mirror a rotate event.
Press the MIRROR soft key.
First Event #: is the event number of the first event to be mirrored.
Last Event #: is the event number of the last event to be mirrored; if only one event is to be mirrored, the last event is the same as the first.
Cutting Order: input 1 to cut from the lowest mirrored event to the highest (forward) and 2 to machine from the highest mirrored event to the lowest (backward). This way you can keep all the machine motion in a consistent direction as it moves from the original shape to the mirrored shape and keep all cutting either climb or conventional.
Mirror Axis: is the selection of the axis or axes to be mirrored (input X or Y or XY, SET).
X Offset: is the distance from Y absolute 0 to the Y-axis line of reflection.
Y Offset: is the distance from X absolute 0 to the X-axis line of reflection.
ROTATE
Is used for polar rotation of parts that have a rotational symmetry around some point in the XY plane. In other words, you will rotate the geometry around the Z axis. In addition to specifying the events to be repeated, you must also indicate the absolute X and Y position of the center of rotation, the angle of rotation (measured counterclockwise as positive; and clockwise as negative), and the number of times the specified events are to be rotated and repeated. You may not rotate another rotate event, however you can rotate a mirror event.
Press the ROTATE soft key.
First Event #: is the event number of the first event to be rotated.
Last Event #: is the event number of the last event to be rotated; if only one event is to be rotated, the last event is the same as the first X Center: is the X absolute position of the center of rotation.
Y Center: is the Y absolute position of the center of rotation.
Angle: is the angle of rotation of the repeated events (positive is counterclockwise; negative is clockwise).
# Repeats: is the number of times events are to be rotated up to 99.
COPY
Copy Events are programmed exactly like Subroutine Events. The only difference is that in Copy the events are rewritten into subsequent events. If, for example, in event 11 you Copy Repeated events 6, 7, 8, 9, 10 with 2 repeats, events 6-10 would be copied with the input offsets into events 11-15, and recopied into 16-20.
Copy Events may be Repeat, Mirror, Rotate or Drill to Tap.
Copy is very useful. With Copy you can:
Edit the events that are being repeated, mirrored or rotated without changing the original events.
Connect so that the quill will not move up to the Z Rapid position, and back down unnecessarily. However, to be connective, you must be certain that the X, Y, Z begin of the first event, once offset or rotated, coincides with the X, Y, Z end of the last event.
Program an event parallel to X or Y (where the geometry is the easiest to describe), rotate it to the desired position, then delete the original.
Copy Drill to Tap
Do not use this, as the floating tapping head is not available.
PAUSE
The purpose of the Pause Event is to allow you to program a stop condition within the program. The effect of this event is to turn off the spindle, move the head to the Z retract location with the X and Y position corresponding to the end of the previous event and stopping the program run.
Pause events are useful if you want to stop the program to make a measurement, change a fixture, etc.
NOTE: In general, you should avoid programming a PAUSE event between two connective events. The Pause event will cause the events to NOT be connective.
To program a Pause Event press the PAUSE soft key. Because there is no input required, simply press SET to load and the event counter will advance by one and the Select Event screen will reappear.
In run, press the GO key after a pause to continue.
Engrave
The Engrave Event allows you to machine numbers, letters and special characters as part of a part program.
When programming with the Engrave Event, the ProtoTRAK will construct a box to contain the text you define. This box is oriented along the X axis like the text in this sentence, and you may program up to 40 characters per event (although you will only be able to see 20 characters on the prompts screen). To machine text in a direction other than the X axis, simply use multiple Engrave Events and place the lower left corner of the box wherever you would like. The numbers and letters you program will always have a standard orientation (like the letters on this page) – you cannot program tilted or inverted letters with the Engrave Event.
Prompts for the Engrave Event:
First, define the lower left corner of the box that will contain your text:
X BEGIN: The X coordinate of where you want your text to begin.
Y BEGIN: The Y coordinate of where you want your text to begin.
Z RAPID: is the programmed position you want the Z rapid to stop and the Z feed rate to start. Always program this at .1 above the part. NOTE: If Z zero is the top of the part, set Z rapid at .1.
Z END: The Z dimension to the bottom of your text.
HEIGHT: The height of your text. Each character varies in width; the set height of the character will change the width in order to keep the overall size of the character proportional.
TEXT: The text to be milled. When you get to this prompt, the Alpha keys will automatically pop up to allow you to enter the text. Once you have finished entering text, you must press End (F8) and then any of the SET keys to successfully enter your text into the event. The alpha keys will appear automatically if the text field is blank. If you have already entered text but wish to make a change, you will see a blue question mark appear on the lower left corner of the screen when you scroll to this field, press the Help button and the alpha keys will appear.
RPM: is the spindle RPM for the event. INC SET will use the RPM of the previous event.
Z FEEDRATE: Is the feedrate from Z rapid to Z end.
XYZ FEEDRATE: The feedrate of XYZ along the path of the text.
Tool #: is the tool number you assign.
Notice the field that is labeled “Text Length”. This field will display the total length of your programmed text and will update as you enter each character.
Auto Geometry Engine (A.G.E.) Programming
This entire section deals with the Auto Geometry Engine.
When you program an Irregular Pocket or an Irregular Profile the Auto Geometry Engine, or A.G.E. is automatically started.
Unlike other events, the A.G.E. allows you to:
Enter the data you know, and skip the prompts you don’t.
Use different types of data (like angles) that may be available from the print.
Enter guesses for the X and Y ends and centers not available on the print.
With the A.G.E., you can easily overcome limitations in the data the print provides without having to spend time in laborious calculations.
The A.G.E. is started automatically when you enter the Irregular Pocket or Irregular Profile event. The first set of prompts you encounter will be the header information.
Once the profile header screen is finished, you choose between an A.G.E. Mill and an A.G.E. Arc to define the shape.
Where:
A.G.E. Mill: A straight line from one X Y point to another.
A.G.E. Arc: Any part of a circle.
End A.G.E.: Ends the A.G.E. programming for the Irregular Pocket or Irregular Profile.
Abort A.G.E.: Aborts all A.G.E. events. The data for all the events is lost.
A.G.E. Mill Prompts
Press the A.G.E. Mill key.
Prompts in A.G.E. Mill programming:
Tangent: this refers to the tangency of the mill to the previous event.
X END: is the X dimension to the end of the mill cut; incremental to X Begin.
Y END: is the Y dimension to the end of the mill cut; incremental to Y Begin.
Warning
Use INC SET for CONRAD, ANGLE END and LENGTH input.
CONRAD: is the dimension of a tangential radius to the next event.
ANGLE END: is the angle measured counterclockwise from this mill event to the next. Do not input if the next event is an arc.
LENGTH: is the length of the mill from beginning to end.
LINE ANGLE: is the angle of this mill line (moving from begin to end) measured counterclockwise from the positive X axis (that is 3 o’clock).
GUESS: This softkey will appear when the prompt is on X or Y dimensioned data. Press the Guess key before you press INC SET or ABS SET to enter the data as a guess.
A.G.E. Arc Prompts
Press the A.G.E. ARC key.
Prompts in A.G.E. Arc programming:
Tangent: this refers to the tangency of the mill to the previous event.
DIRECTION: is the clockwise (input 1), or counterclockwise (input 2) direction of the arc.
X END: is the X dimension to the end of the arc cut; incremental is from X Begin.
Y END: is the Y dimension to the end of the arc cut; incremental is from Y Begin.
X CENTER: is the X dimension to the center of the arc; incremental is from X End.
Y CENTER: is the Y dimension to the center of the arc; incremental is from Y End.
CONRAD: is the dimension of a tangential radius to the next event.
RADIUS: is the radius of the arc.
Warning
Use INC SET for CORD LENGTH, and CHORD ANGLE input.
CHORD LENGTH: is the straight line distance from the begin point to the end point.
CHORD ANGLE: is the angle spanned by the arc.
In addition to the normal Softkeys, this additional one will appear in A.G.E. Arc programming:
GUESS: this softkey will appear when the prompt is on X or Y dimensioned data. Press the Guess key before you press INC SET or ABS SET to enter the data as a guess.
Skipping Over Prompts
In the A.G.E., events don't have to be fully defined before you can go to the next one. You can skip the data you don’t know by using the DATA FWD softkey. After you press the DATA FWD key at the last prompt, the event will move to the left side of the screen and the Select Event screen will appear.
When skipping over prompts or editing, always use the DATA FWD or DATA BACK key.
Using INC SET or ABS SET will change the data.
If you want the event back on the right side, use the BACK hard key.
The OK/NOT OK Flag
Each A.G.E. event has a flag that tells you if it has been fully defined. Sometimes data from later events is needed to define previous events. To the immediate right of the event type, the words OK or NOT OK appear, depending on whether that particular event is defined.
Once the OK flag appears for the event, you do not need to enter more information.
Skip past the rest of the prompts with the DATA FWD softkey.
If you leave the Program Mode and then return, pressing the GO TO END softkey will take you automatically to the first NOT OK event.
Ending A.G.E.
Any time all the events are of an Irregular Profile are OK, the A.G.E. may be ended. If you are programming an Irregular Pocket, there is an additional requirement that must be satisfied before the A.G.E. may be ended: the X and Y end point of the last event must be the same as the X and Y beginning point, so that the pocket is closed. Otherwise, the ProtoTRAK SMX CNC cannot program the tool path to clear the pocket.
The Irregular Profile has no such restriction since profiles may be open or closed.
Once the A.G.E. is ended, the Irregular Pocket or Irregular Profile event is complete and you may then choose from all the programming canned cycles from the Select an Event screen. To reopen the A.G.E. Profile or Pocket, simply use the BACK hard key or the PAGE FWD or PAGE BACK softkeys to position on of the A.G.E. events on the right side of the screen. You may edit or insert other events.
Guessing Data
Whenever you are missing X or Y Ends or Centers, you should generally enter a guess. Guessed data is treated differently by the ProtoTRAK SMX CNC than regular data. Often, the information you put into the system will allow it to calculate a mathematically correct line or arc that would satisfy the conditions of the hard data you entered. This line or arc may yield more than one solution to particular point you are looking for. That is where the Guess comes in: the A.G.E. uses the guess to choose from the mathematically possible solutions. In most cases, your guesses do not have to be very precise. The smaller the lines or arcs, the more precise the guess should be.
Guesses should always be entered as absolute dimensions. Once entered, the guessed data is green and there is a 'G' next to it. Guessed data will be labeled this way in all the events that are flagged NOT OK. Once an event is OK, the guessed data will be replaced by calculated data. If you wish to edit your guesses, placing it on the right side of the screen will cause your original guessed data to reappear.
LOOK and Guess
Guessed data may be entered by pressing the number keys and then SET. However, you may find it more convenient to use the LOOK graphics to enter guesses.
When the highlight is on the prompt for which you wish to enter a guess, press the Guess key. The Data Input Line will say "Enter Guess for X END" (for example). At this point, press the LOOK key.
When the Data Input Line says "Enter Guess" pressing LOOK gives you the ability to use graphics to make your guesses.
The Data Input Line could say "Enter Guess for X BEG". Pressing LOOK at this point will take you to a special version of the LOOK graphics. Using the cursor keys, you may move a point around the screen. When you come to the place where your point is, use the Enter key.
The softkeys for this special version of the LOOK graphics:
UP, DOWN, LEFT, RIGHT: move the cursor around the screen.
ZOOM IN: makes the drawing larger.
ZOOM OUT: makes the drawing smaller.
ENTER END: when the cursor is at the point you want to use as a guess, use this to enter the end point of a line or an arc.
ENTER CENTER: use this to register a guess for the center of an arc.
You can enter a combination of guessed and non-guessed data. For example, if you were to enter the dimension for X End without guessing, you would still be able to enter the dimension of Y End using guess.
Your guess entries are loaded into the program when you exit the LOOK screen by pressing BACK or by pressing LOOK again. The ProtoTRAK will use the last ENTER key press and load that into the program.
When you use the graphics to guess dimensions on arcs, you may load in guesses for both the X/Y End and the X/Y Center before leaving the LOOK screen.
When you have not first pressed the Guess key, pressing LOOK gives you the same screen as in regular programming. Whether you enter the guesses as key presses or by using the graphics, the drawing of the LOOK screen distinguishes between events that are fully defined and those that rely on guessed data. OK events are represented by solid lines. NOT OK events are represented by dashed lines.
When the events are calculated based on Guessed data, they are represented by a dotted line.
Calculated Data
Prompts that are skipped or for which guesses are entered may be replaced by data calculated by the ProtoTRAK SMX CNC. Calculated data is shown in red in order to distinguish it from the data that you entered. You cannot edit calculated data, but you may edit your original input. By putting the event with the calculated data on the right side of the screen, you may position the cursor to the prompt and re-input the data.
Arcs and Conrads
If the print is missing a lot of data, it may be desirable to program arcs as separate events where possible. This gives the system more information to work with.
Tangency
Tangency can occur between a mill and arc or an arc and arc. Specifically it means that the two events share one and only one point. You would answer yes to the TANGENCY prompt if the event you are programming is tangent to the previous event. The information that events are tangent helps the Auto Geometry Engine calculate other dimensions.
You can often tell by looking at the print if events are tangent:
Tangent intersections tend to blend smoothly without a sharp corner.
Smooth, probably tangent.
Sharp, not tangent.
For the A.G.E., the tangent mill or arc is assumed to continue in the same direction, and not double back on the previous event.
Loading CAM Programs
Warning
Before loading your program, see shop staff to have your program verified.
Place your USB into one of the ports on the right side of the pendant.
Press MODE, and select PROG IN/OUT.
Make sure "List Supported Programs Only?" says YES. If not, press YES.
Press OPEN.
You will now use TAB to find the D: drive and use DATA FWD or DATA BACK to highlight the folder your program is in. Once the folder is highlighted, press OPEN FOLDER. If you can see your program in the window, you can move ahead to OPEN FILE.
Now that you can see your program, use DATA FWD or DATA BACK to highlight it, and press OPEN FILE . If you can't see your program, see shop staff.
Your file will now be loaded into the memory of the controller. Press PROG and GO TO BEGIN, GO TO END, or GO TO # and select an event number, to see your program.
LOOK
At this time you can also press LOOK to see the graphical representation of your cutter paths. It gives you the ability to see your cutter paths in the XY, YZ, and XZ planes, as well as 3D.
LOOK only works while you are in the program. Press MODE, PROGRAM, BEGINING, then LOOK.
Tool Change Reference Position
Note
Set the Tool Change Reference Position to the right of the vise.
Press the MODE, SET UP, and REF POSN to set the tool change reference location.
From here you can hit the JOG and manually move the X, Y, and Z axis to a safe, suitable location for changing tools in and out of the spindle. The Z-axis needs to be moved high enough above the workpiece to allow your longest tool to easily clear the top of the part when it is being inserted into the spindle.
Press RETURN once you have located the X, Y, and Z axis in the position you want. The reference position page should pop back up on the screen. Use the UP/Down arrows to highlight the words NOT SET if not already highlighted, and press ABS SET. Notice it changes to SET and the cursor automatically moves to X HOME. Press ABS SET twice more to enter the X HOME and Y HOME locations into the reference position page. (These are the actual locations which the machine table is currently positioned.)
The DPM2 will now move to the current table location each time a tool change is called for in a program.
Press MODE to exit the Tool Change Reference Position page.
If the DPM2 is in 2-axis mode, you will not see NOT SET on the reference page.
Caution
Do not set the limits.
Tool Setting
Note 1: You will be 3-axis machining, be sure to select that option prior to setting the Tool Setting Gage Reference Position in the tool offsets page. (This is located under the SYS button). You will still need to follow this procedure for 2-axis machining.
Note 2: Load your program prior to setting Tool Setting Reference Position in the tool offsets page.
Before setting any tool length offsets, you must set a Tool Setting Reference Position. You will need a reference tool used in conjunction with the tool setter in order to accomplish this.
Setting the Tool Setting Reference Position
- Load the reference tool into the spindle. Move the table until the spindle is roughly located over the back vise jaw.
- Set the tool setter on the back of the vise, just behind the back jaw. Make sure the block and vise are clean.
- Align the reference tool directly over the tool setter (use the X & Y axis hand wheels if necessary).
- Use JOG to move the Z-axis down until the tool setting gage standard is within 3 to 4" of the top of the tool setter.
- Hit RETURN to take the machine out of jog mode.
- Use the manually operated quill feed lever to carefully lower the reference tool until it aligns the needles with 0 on both the outer diameter, and the small scale simultaneously. Lock the quill in place once contact has been made.
- If you are not already in the Tool Table page, hit MODE, SETUP, and then TOOL TABLE. Make sure the cursor is highlighting the words NOT SET under the Z offset column and press ABS SET.
It should now read SET under the Z offset column.
Setting the Tools
Warning
Do not fill in the diameter column when running a CAM program, as this will cause the machine to alarm out when trying to run the program. However, be sure to add the diameters while running a conversational program.
- Move the cursor to the Ref 1 position, all the way to the left under the DIA column. Raise the spindle. Press JOG, followed by the Z-axis button to move the Z-axis up until you can safely remove the reference tool and load tool #1 as set in your CAM program (use the +/- key to change directions of jog for each axis).
- Once tool #1 is loaded into the spindle, slowly jog the spindle down to within 3" of the tool setter. Stop jogging and use the manual quill feed lever to carefully lower the tip of the tool until it aligns the needles with 0 on both the outer diameter, and the small scale simultaneously. Press RETURN to get back to the TOOL TABLE page. Make sure the cursor is still in the Ref 1 postion, all the way to the left under the DIA column.
Warning
When the tool is touching the tool setter, moving the x or y hand wheels will damage the block and tool.
- For 2-axis only, enter the actual diameter of the tool and press ABS SET. You should now see the diameter you entered displayed in the Ref 1, Dia 1 column. The cursor should automatically move to the right, highlighting the Ref 1, Z-Offset column. Press ABS SET again and the Z-axis number you noted on the DRO page will automatically be loaded into the Ref 1, Z-Offset column.
The cursor will again move to the right, highlighting the Z-Modifier column. Pressing the ABS SET key will load this column with zeroes and move the cursor to the right. It will also bring up a small green pop-up window containing a table of 14 different tool types. Enter the number which best describes the tool you currently have in the spindle, followed by ABS SET. A description of the tool will appear on the screen under the Ref 1, Tool Type column. (Example: if you have a roughing end mill in the spindle, enter the number 3, followed by ABS SET. Rough end mill should now appear in the Ref 1, Tool Type column.
- Manually raise the quill feed lever to its highest position, press JOG and move the spindle up high enough to remove tool #1 and load tool #2. Repeat the process for all of the tools in the program you intend to run.
Zero Location
UCS
The UCS is the same as the X, Y, Z zero location you set in your CAM program. These must match or your part will be machined in the wrong location on your material.
Set X & Y Axis Zero
- Load a drill chuck into the spindle, and load an edge finder. Press DRO, then SPIN SPEED.
- Enter between 600 and 800 and press ABS SET.
- Rotate the spindle on/off switch clockwise to the #2 position. The spindle will now be rotating clockwise at between 600 and 800 rpm.
- Use JOG to position the edge finder within 3" to 4" of the top of the part.
Warning
Do not use JOG once you are within 3" to 4" of the part in any axis!
- Use the X & Y axis hand wheels and manual quill feed lever for fine adjustments. You risk crashing into the part or vise if you don't, which could damage the tool and/or spindle.
- Press MODE and DRO to deactivate the JOG mode and keep the DRO page active.
- Lower the edge finder just below the top of the part and manually bring it close to the left or right edge of the part. Once you are close, switch to the fine increment hand wheel mode by pressing F on the F/C button. (F/C stands for Fine and Coarse increment)
- Use the edge finder to locate the edge of the part and rotate the on/off switch to the O (off) position. Manually retract the quill until the tool is just above the work piece. Use the X-axis hand wheel to move the edge finder over the top of the part by 1/2 the diameter of the edge finder.
- Press X then ABS to zero the X axis.
- Repeat these steps to set the Y-axis.
Note: If you want to set the zero in the middle of your stock, do so at this time. See shop staff if you are not sure how to.
Set Z Axis Zero
Warning
Before you can run a program, you must set a Z-axis zero point on the part in the DRO mode. This must be done after all tool lengths, diameters and descriptions have been entered. Use tool #1 to set the zero.
- Press MODE, DRO and TOOL #. Enter 1 followed by ABS SET. You should see TOOL #1 appear in one of the boxes near the top right side of the screen. Do not continue if you don't see TOOL #1 appear!
- Use JOG to move the tool down to within 3" to 4" of the top of the workpiece. Press RETURN to stop jogging at this point and use the manual quill feed lever to bring the tip of the tool down until it just barely touches the top of the part. Instead of touching the stock, use a piece of shim stock between the tool tip and the top of the part as a feeler gage. Remember to account for the thickness of the shim stock which is .010".
- Once you are satisfied that the tip of the tool is indeed on the same plane as the top of the part, lock the quill in place.
- Press the Z-axis button followed by ABS SET while in the DRO page to set your Z-axis zero point.
Fixture Offsets
Use Fixture Offsets only when you have more than 1 part that needs to be set up at the same time.
Unless you are running multiple fixtures, do not enter anything into the Z-OFFSET column at this time.
Warning
Do not use. See shop staff before attempting to set up.
Running Programs
Warning
Before running your program, see shop staff to have your program verified.
To run your program, press MODE, RUN, Start and then TRAKing. TRAKing allows the operator to control the feed using the X and Y axis hand wheels. The X axis hand wheel is the coarse feed and the Y Axis hand wheel is the fine feed. The operator will use TRAKing to verify that the Z offset is set correctly for the current tool at the start of each operation. Once it is determined that the Z offset is set correctly, the operator can press the Stop feed button on the top right corner of the controller, then press CNC run and press GO or double click the button on the hand held pendant.
START EVENT # allows the operator to start at a know event number.
TRIAL RUN allows you to quickly check out your program with no Z movement before you actually start to make parts. In trial run, the table will move at rapid speed regardless of what feedrates are programmed (the rapid speed may be overridden with the up/down arrows). The table will stop at each "stop" location (for example, at each drill location) but immediately continue on without your input.
Note
When you are ready to begin running the program, see the shop staff to learn about the Traking feature on this machine.
Shut Down
Warning
The computer on the Trak DPM2 is Windows based and therefore must be shut down properly in order to protect it!
- Press SYS.
- Press SHUT DOWN.
- Press YES and wait for a message to appear on the screen. It will say "It is now safe to turn off your computer".
- Flip the toggle switch located on the right side of the pendant to the "DOWN" position.
- Rotate the ON/OFF switch located on the back of the machine to the OFF position.
Caution
You need to clean the machine before turning in your tools! Watch the video to see the proper way to clean the machine. Click HERE to see the video.
Troubleshooting
How do I load my program if I got an error saying my program is too large?
If you receive an error when loading your program that states your program is too large, you can load the program as a g-code program. Highlight your program, then Tab until you find the OPEN AS window. DATA FWD or DATA BACK until .GCD is highlighted, then OPEN FILE.
Can I edit my program as g-code?
Press EDIT, and you are now allowed to press G CODE EDIT.
The next screen shows you the program in g code form. You can use the SEARCH to locate the line of code, speeds, feeds, or any other individual piece of the code you may need to modify.
Note
You will need a keyboard to edit the g-code. We do NOT have a keyboard on this machine. Re-post your program, rather than trying to edit the g-code at the machine.
Why are drills are moving in my drill chuck?
You need to make sure the drill goes in as far as the chuck will allow, without clamping on the flutes. If needed, use a smaller drill chuck.
Why is the screen flashing a "Out of Range" warning?
You have exceeded the speed range of the spindle. Check to see if you are in low gear. If you are in the correct gear, make sure you haven't set your spindle speed higher than the machine maximum of 5000 rpms.
