Have a VM4222IL and making a part with
6 bolt hole 3/8-16 at a 7.5" diameter
There is a bolt hole program in conversational, it can tap also. Wanted to thread mill this part.
There is a thread mill program for a single hole. But can't find one that does the bolt pattern to save time in programming.
Any ideas?

I would create the thread mill code as a subroutine and the use positioning to the center of each hole to be machined
The bolt hole cycle is probably only allowing you to use G81-G85 ---drilling thru boring cycles
i am not familiar with your control as to how you will do subs but this is what i do for a haas control
