CAM Setup Basics: Zero, Stock and Workholding Before Toolpaths

Practical workflow

1. Confirm model orientation matches how the part will actually sit in the machine.
2. Define stock dimensions and offsets intentionally rather than accepting defaults blindly.
3. Choose a work origin that can be located consistently on the physical setup.
4. Model or account for vises, clamps and fixtures where collision risk exists.
5. Verify tool reach, holder clearance and setup accessibility.
6. Simulate the complete operation and review rapid moves before posting code.

Use the guide as a starting point

Machine, material, software and manufacturer requirements vary. Keep a controlled test record and use the current documentation for your exact equipment and process.
