|
|
I'm trying to learn to program a Okuma CNC Lathe and am having difficulty with a aspect of the program. I'm trying to use G85 to cut a bore but the machine wants to rapid into the part and feed out instead of doing just the opposite. Here is my code, please let me know when is wrong with it. I'm learning from the book and it just isn't helping me.

I finally figured this out. The key was to program it from the outside to the inside, but position the tool at the inside to begin. Here was the final code that worked. Thanks for all the help.
