I have a single flute 1/16" upcut end mill designed for cutting acrylic sheet. I’m cutting 3mm thick sheet running at 6mm/sec with a .8mm depth per pass at 30000 RPM. The cut is great, until swarf sticks to the bit, pretty much on the second pass.
I can slow the RPM a bit, but not certain of exact RPM.
I don’t seem to have this trouble with a 2 flute bit at 12mm/second feed rate with the same depth per pass.
Anyone have any ideas why? I have an idea, but before trying I figured I’d see if someone sees any glaring issues in my setup.
