Custom thread

[Thoob]

Good morning guys, I've been tasked with looking at cutting a very large thread, and I noticed the custom thread option in mastercam. What I'm trying to do is an oversized buttress thread. I've done my best to put in all the parameters and the machine seems to accept everything and is cutting fine. I'm using  round edge took for testing. What's happening is that during the thread cycle, using G32, it dwells at the end of the thread instead of pulling out causing a groove. I don't typically use the g32 cycle. Anyway, I don't know if there's an option to prevent that or if it's just the g32 that is doing it. Little help?

After playing around with the cycle, it seemed that the switch from G32 to G00 had a split second delay, which was causing the groove. I changed the G00 to the next line in Z after retract and it works fine now. Only thing is that it retracts in inch/rev. A thread with an undercut should never experience this problem.

A google search of custom threads just in case you are in need of further edumacation on said topic.

My history with Fanuc, I believe It's a parameter setting. Pull out or Dwell and pull out.

Not too sure about this though as normal threading retracts fast, as normal.
