Very little force is needed. We often cut shapes out of 2" foam in one pass
at 4.8 m/min (approx 190ipm) with a 1/2" cutter spinning at 18000 rpm. Dust
extraction is essential otherwise the whole room will have an even coating
of foam dust!
If the cutter is sharp you end up with a finish at least as good as hot
wire.

How much force does it take to cut foam with a CNC router? I've
searched the web but only found references for hot wire cutters. I
would like to get a handle on just how beefy you have to make a foam
router, I suspect a lot less than a wood router. It seems that wire
cutters don't take much beef. Any experience or thoughts?
