I am trying to cut a light knurl pattern in the bore of a part using a threading tool and our Daewoo 400 with Fanuc 21i-TB control, the problem is I have to start and stop the thread tool in a narrow groove, I can do this on our Mori Seiki SL-25 with a 15T control with a G76 by using a Q to command what degree the thread starts at, however on our Daewoo 400 Q is a depth command and looking through the books I can't figure how to do a multi-start thread and have the same start point in "Z", any ideas??? These parts are too big to fit in the Mori or I would use it.
