Advice on converting Machine Code from Imperial to Metric

[Stressedwoodman]

A bit of a stupid question, which shows my ignorance in NC coding. These imperial programs I am using have a tool change callout G43. This line is causing me an issue on some of the latter programs I am running, as I have limited Z axis travel and don’t have the luxury of allowing the spindle to go to Z1 an inch above the work piece. It’s weird why the programs have tool changes specified as it’s all one tool.

Can I simply remove the line from the programme ... or do I just modify it to say Z0.25. I am not clear whether the program refers back to the tool change or not. I have searched the program and it only has one g43 callout.

G43 is tool length compensation, so if you have not set any tool lengths in your tool table then you can just delete it. Or you can just change the Z value.
Somewhere in your CAM program, you will have a setting to change the Z value.
