Re: [CAD_CAM_EDM_DRO] Force for foam cutting

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.
