My shop is making a part that has 4, 3/4-16 holes on the face. We are using a single point thread tool to cut the threads. It is programmed in X and C, posted off of Gibbs. When ever you need to open up the threads, you need to go to programming and have them make the changes and re-post it. It takes 36 pages of code to make .700 of threads in one hole! I'm trying to get them to re-program in X and Y, and use cutter comp, but they are having trouble getting it to work. I tried to write a variable program for this, using a variable for the cutter dia, kind of a hand-made cutter comp, but I'm pretty rusty at this. I can get the thread tool to the center of the hole, but it wants to cut the threads off-center. Anyone got any ideas? Thanks alot.
