Re: CNC programming, just getting started cnc mill, tool length offset question
I am sure this will quickly veer off to crazy places, but if I were you just starting out, I would keep it very simple.
Set up you part up in the vise or however you need, then touch your tools of of the top of the part. All tools will clear during rapids etc. all programming will have negative Z values. Most every Cad-Cam system writes programs normally in that mode. Z zero is the top of the part and all cutting Z moves are negative.
Have fun-------Mike
