lathe internal threading with single point tool

leo.castellon — Mon, 16 Aug 2021 17:09:27 GMT

I am trying to turn an ID thread into some 17-4 blanks and these are rather expensive blanks so I don't want to screw them up. I know I can thread mill them and I have the tools for it, but I would like to try it on the lathe. My problem is trying to define the thread tool. I am using an Internal Tool, 60 degree profile single point tool to cut a 1/2x13 thread.

Any suggestions? The tool is shown in the attached photo.

I'd define it like so:

Other than that, it's pretty straight forward, nothing to be concerned about.

Do you have a piece of setup material you can use to prove out your code? I always try to have something of similar size in my shop, whether it's brass, aluminum, plastic, anything really. While it doesn't prove out your cutting parameters, it beats the heck out of having to tell your customer you scrapped a part

Thanks for looking at that. This is one of those crazy rush job parts so to play it safe I am going to thread mill it. When I have time, I will set up a dummy part and try your method out.

Okay. Now the same question but for a #8-32 thread...
