hi everybody,

how can I do that in mastercam?

thanks.

Thread milling, turning, or tapped?

Hello,

 

We are about to get a CNC lathe and I am looking into how things are done. One thing I am curious about is how to cut an NPT pipe thread. Is there any tutorial I can look at that shows how a program is set up to do that? Anyone have any advice for me that has done it before?

 

Best regards,

Using Mastercam you set the 1.78333 taper angle and you have a tapered pipe thread. All you need then is the gauges and you are done.

For X2

 

Go to lathe tool path, thread, thread shape parameter, in thread form scroll down to NPT, pick thread needed, back in thread shape parameter click on draw thread. Click yes for save geometry.

 

You will now see the major and minor diameter for your thread and can use this geometry for creating a turned profile on the part as preparation for threading.

 

I'm not sure how this differs in X3 and X4.
