    At the moment I have a 6 mm 4 flute end-mill (broke my 3mm and still waiting for more bits to arrive). I need to cut a shape out of 4 mm acrylic, but I'm not sure the speed & feed-rates I'm using are correct(16000 RPM with a feed rate of 550). I've just had a go at the on-line FS Wizard and it looks fairly decent, but a little complicated - so I'm not sure if I'm setting it up correctly(it gave me 16000 RPM with FR 1623).

    What speed/feed rates would you guys recommend for cutting acrylic with a generic 6 mm 4 flute end-mill?
