I have been cutting acrylic today, trying to get a nice clean cut. So far I’m still getting a bit of a “bumpy” edge. Below are the settings that turned out the best. I used carpet tape to hold the material down, being careful to keep the tape away from the cut line.
My feed rate was set to 2000mm per minute and my spindle was set to approximately 18000RPM. I was cutting 2.2mm in a single pass.
I used a 1/8" single flute upcut bit: https://www.inventables.com/technologies/solid-carbide-single-flute-upcut-end-mill
Any ideas of how I can improve my cut? I appreciate any help!
