CNC feed/speed settings?

Discussion

Hi, I need to cut a sheet of tufnol on CNC
(dense heat-resistant phenolic composite plastic, cotton reinforced, non toxic dust - safety sheet)

What speeds should I use? It is a PCB-like material, and I need to use smth like 2mm cutter, but I didn’t find any settings for this in the library (there are no tools set for PCB). How do I approach this?

You’re talking about the desktop CNC?

Yes.

Have a look here:

Seems high speed, slow feeds are the way to go, and you will want to break your job into relatively short runs so you can hoover out the dust frequently.
