Material Requirements
Part A
-
Pair of 1-1/4" parallels with a 6" vise. See pro staff if you're not sure.
- Parallel keeper
-
Edge finder
-
8” caliper
- You will want tools as short as possible so they are as rigid.
-
Tools required:
- Tool 1: 3/8" 118 degree spot drill
- Tool 2: #7 drill (.201")
- Tool 3: 1/8” drill
- Tool 4: 5/16” 5 Flute uncoated carbide end mill
- Tool 5: 3/32” 4 Flute uncoated carbide end mill.
- Tool 6: 1/2" 4 Flute Chamfer/Drill Mill (Set up as a countersink tool in the tool page so the verify looks like it should, selecting "Endmill" will make the verified part look odd.)

Operations
Part A
- Refer to the TRAK TMC 7 mill guide to complete operations listed below.
- Use the Enhanced ProtoTRAK Assistance(EPA) at anytime while using the machine. (Not really needed but it is there for reference)
- Plug in the thumb drive and load the E:/programs/CNC Mill 3 Upgrades/M3-A1.GCD file.
- Mount the program tools into appropriate tool holders and place them in order on the tool cart. At no point should the air blast nozzle be used to blow off machine/vises/parts without a tool in the spindle!
- Note: When using the collet chucks, be sure the collet, collet nut, and holder are clean of chips,dirt/debris, and coolant!
- Take the nut off the holder and push the collet into the nut until it clicks. Screw the nut back on the holder. Place the tool into the collet and use the designated spanner wrench to tighten. Make sure that the nut is tight!
- Set, (Teach), the reference(base)tool in the tool table.
- Set tool 1 in the tool table the same as you set the base tool.
- Set tool 1 in the 1 spot in the ATC.
- Respeat steps 7 and 8 until all tools are referenced in the tool table and are in the ATC in order.
- Secure the stock in the vise and set X0,Y0 in the center of the stock, using the edge finder.
- Use paper to set Z 0 at the top of the stock. Make sure the tool that you are using to set Z 0 is identified at the top of the DRO page.
- Go to the Set up mode and select verify part.
- Select define stock to set the size of the size of your part.
- Select make part and then select verify part to show your tool path.
- If the verify looked good, then you are ready to start machining your part.
- Use tracking at the start of each tool to make sure Z axis for each tool is set correctly, watch the DRO page!!
Part B
- Refer to the TRAK TMC 7 mill guide to complete operations listed below.
- Use the Enhanced ProtoTRAK Assistance(EPA) at anytime while using the machine. (Not really needed but it is there for reference)

Frequently Asked Questions
What is TRAKing?
TRAKing allows the user to control the X,Y and Z feed with the use of the hand wheels, located at the front of the machine! The right side hand wheel is the course feed and the left hand wheel is the fine feed. It is required to use TRAKing at the start of every tool change to make sure that the Z offset is set correctly for each tool.
Troubleshooting
Why is my Z offset wrong?
The user may have set the Z offset with the wrong tool. For example; If you set the Z offset with tool 1, the tool # on the DRO needs to be set at tool 1. Most of the time the user will set tool 2 into the tool table and forget to change the tool number back to tool 1 to set the Z offset.
