Need Help!- Finding NPT taps for Mastercam X

[rackthis]

I can't find any NPT taps in the Mastercam tool library. Any help would be great. I was thinking I could just make ny own tool, but don't know the parameters for setting the depth, feeds and speeds for NPT taps. Thanks.

And you won't because it's not there. You will have to create your own tool and the feeds and speeds too.

Hmm, don't know if I'd bother to machine tap NPT threads, as I've yet to see a spiral point NPT tap.The torque required to drive the tap in would be pretty high. I'd venture a guess that most people would thread mill that kind of a profile (provided the control can do it). This would give you exact control of the number of turns (3-1/2 typ.) until a wrench is required.

I was able to find the feeds and speeds for the npt taps. I made a new tool in the tool manager and going to try it out today. I do realize that it does take alot of torque to use the taps, but I have done it before on this machine and it has done it well, as long as you don't go too deep. Thanks for the help. I will let you know if it works and post the information.

rackthis,

please lets us know your results.

I run a makino 1210 maching center, and havent yet hand tapped a npt threaded hole. never had a problem with the 3-1/2 turn either. cimco feed and speed calculator works pretty good to calculate ur speeds and feeds, you can dowload it free from the cimco website.
