To use The CNC Broach Tool Program Generator:

1. Choose your machine type: Lathe or Mill. 
2. Select the type of program you want to export: Long format or Sub Program
3. Select which tool you’d like to use
4. Enter the Bore Diameter, Keyway Width, Radial Depth, Z axis start & end points, Depth of Cut, & IPM.
5. For milling machines enter the feed axis and feed direction
6. Accept the Terms & Conditions
7. Copy the code (Ctrl C) and paste (Ctrl P) it into your program
8. Try the new V2 program generator
9. Try the full version of CNC Machinist Calculator Ultra.

Z axis start point: The start point should be at least .500″ above the bore face to allow for acceleration prior to cutting.

Z axis end point: The end point must clear the back face of the bore by at least .200″. This is important because some machines will actually begin to retract on X or Y prior to reaching the Z end point. This “Phantom Retraction” could cause the insert to pull out of the pocket. The insert must be completely through the material in the Z axis prior to retracting on X or Y. One way to avoid the “Phantom Retraction” is to add an exact stop g-code to your program. This will slow your broach cycle considerably, however. This is why we recommend extending the Z axis end point instead.
