How do you Thread Mill??

[nickelback]

Hi guys

 

I would like to know how to use the parameters in the thread milling operation. I know very little and I can't find anything in the help file or in any of my books. Is there something out there for me.

 

Thanks rjust

Thread milling that I have done involved using a threadform inserted cutter with one flute and usually 8-12 active teeth. Different inserts for different pitches. Mastercam has a parameter for pitch and number of active teeth. Set these acordingly. You'll want cuttercomp so set it up I would use wear comp (comp in control and comp in computer on). Speed and feed depends on everything but you should start about 400SFM on mild steel and .002/rev. If you machine does not support helical moves you will want to linerize the moves.

 

Hope that helps.
