Verify that your controller is compatible with G13 features and update the software to fix known bugs. By doing so, you can prevent G13 code errors and guarantee smooth CNC machining operations.
G13 Tool Path Interference
After resolving controller incompatibility issues, you’ll want to guarantee your G13 code runs smoothly by avoiding tool path interference.
Tool path interference can occur when the G13 command is used with an incorrect radius or diameter, resulting in the tool colliding with the fixture or part geometry.
To troubleshoot G13 glitches, check for these common mistakes:
- Incorrect units for radius and diameter (inches or millimeters)
- Failure to specify the D address for cutter compensation
- Incorrectly specified feed rates or number of passes
Verify that you’ve accounted for tool nose radius when specifying the tool path to prevent interference. Simulation tests can help detect potential tool path interference, allowing you to fine-tune parameters and confirm ideal machining.
