Looking for a threading calculator

[northernmach]

I am looking for a threading calclulator that will give the # of passes for any pitch put into it. I believe I am way to easy on the lathe I run at work and am trying to become more aggressive and productive. I have been told that no 60 deg. single point tool should have to take more than 11 passes. I find that hard to believe without taking away from tool life. Any help would be appreciated. A software that calculates would be great, or even a chart to follow by. Personel inputs are also welcome!

Thanks,
Chad

A VB program should be able to be written to give you some feedback.
What threads are you working with, Metric/UNC/UNF and Whitworth?

These thread calculators have a formula for the same amount of material removal on each pass for a 60 degree thread.

Your welcome Chad!

This forum can solve any manufacturing problem. I learned five ways to remove rusty bolts the other day.

I have Wayne Hills "Thread Quick " from IM Services for my Lathe Retrofit.
I took it over to a friend of mine that had just purchased a very expensive program for his turning center with a funac control..We only had to make a couple of macros for his machine , and I have to tell you, my friend was really bummed out when Wayne Hills economical program performed as good or better, plus it is much more user friendley ( especially since I'm a total computor KLUTZ) than his costley program that requires a yearly fee for "updates" . He and his ass't manager admitted that with Vector CAD /CAM and Wayne's program he could have saved about $18,000.00 plus yearley costs..Thats a bunch for a struggling business.
