So I picked up a 4x4 sheet of 1/4" cast acrylic. I'm going to use it to make a dust shoe for my CNC as well as some guitar building templates for a guy I know. I've read some conflicting stuff online (shocking, I know) about machining the stuff. The cast stuff I got is better for machining than the extruded variety because it's more rigid, so that's a good start. Has anyone here routed acrylic before? Any cutter, rpm and feedrate recommendations? I'm not looking for a glass finish on the cuts but I obviously need smooth cuts if I'm going to cut templates.
