What is the best bit or end mill to use when cutting Acrylic, and what are the best speeds and feeds?
Acrylic is a very common material to cut on a CNC. It can be used for anything from making windows in projects to making edge-lit LED signs. Acrylic can be a tricky material to cut successfully, mainly because many people will run the RPM of the cutter too fast with a feed rate that is too slow, thus causing melting of the plastic. The trick is to get nice clean chips as you cut.
