Newbie looking at 6040 (China CNC) for polypropylene 15mm sheet

Would that mean one should do fewer slower deeper passes, as opposed to faster more shallow passes?

It also depends on your machine, in fact it's mostly about your machine and how stiff it is and what type of cut you're doing. If you're slotting then you have to go slower or shallower than if you're doing a 60% width stepover pocketing pass.

I'm about to cut some more samples (see photos below) at work in Acetal and I'll be doing 20mm deep cuts with a 6mm 2 flute uncoated carbide mill, I'm using Trochoidal milling mind so don't try to take that deep a cut normally!!
