    Default Thread milling a bolt pattern 9000 control

    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?

    Default Re: Thread milling a bolt pattern 9000 control

    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
