Knurling on a CNC lathe?

[Cartierusm]

How do I knurl on a CNC lathe. I'm using Dolphin and the program doesn't have a specific function for it. Any help would be appreciated, thanks.

Like you would on any manual lathe, just use G codes instead of hand pressure.

That said, you should be using a rather rigid knurling tool, definitely not a floating type such as an Armstrong meant for manual lathes. Check with the website for Form Roll Die or Accu Die (the owners of both are feuding brothers.) There's a wealth of knowledge between them, and all the right tools.

What kind of CNC lathe are we talking about here, and what kind/pitch of knurl on what material?

You would program the tool to come in pretty fast, and feed across quickly too. It'll take a little trial & error to get a good knurl, but read up as much as you can first.

We use knurling tools on machines with a physical Y-axis so we found it way faster and easier to align the knurling tool by just using the Y-axis instead of manually adjusting the wheels (centerheight).
