General Mach Discussion / Re: Muti-start threading....
« on: April 20, 2009, 08:33:23 PM »
Hi All,
Been fooling with multistart threading using G76. Have no problem doing single and double start threads
but for some reason a three start thread just dosn't want to come out and haven't quite figured it out.
The third start is always about .002 to .003 inches out in lead and shows up on the third start thread.
I can see the timing is not correct since you can see it on the start of the thread.
Timing or backlash associated?
Don't know.
It was interesting though!
