Hi,
I have some more pretty basic questions about G gode techniques for beginners.
I am practicing trying to write my own code for simple things and today I decided to do circle cuts. I wrote the clip below to try to cut a simple circle and it works but I know its not very good and probably terribly inefficient, but I'm just trying things out a little at a time.
My question is that, while this works, it just plunges the cutter at the begining, and I know that's not best practice. But reading my Tormach manual, the Peter Smid CNC Programming Techniques book, and going thru the G code tutorial at the CNC Cookbook site, haven't shown me the best approach to this problem.
I think I want to ramp into the cut on each pass, but don't know where to learn how to do it? One thought was maybe helical interpolation was the approach, but that's really just a guess.
Any suggestions on where to learn this would be appreciated.
Thanks Terry
