Acrylic routing problem
I'm working in a signs manufacture company and we are machining acrylic. Now the process is that we cut the acrylic with a CNC router, but the finish is not good so we need to sand it, after and we burn the edge to give a perfect transparent finish.
My objectif is to eliminate the sanding process because it is very long.
I tried several bits on the router to give a perfect finish, 1 flute, 2 flute, 3 flutes, spiral, straight, ... my main problem is that I don't know what RPM and feed to use to have a perfect finish and with with bit.
I want to make it in one pass.
Can you help me?
