Has anyone milled “softer” plastics like UHMW polyethylene, and the like? With a 1/8" end mill, it’s cutting like butter. But I’m barely getting any chips - the plastic is so soft that the waste is clumping together in long strands that peel back away from the workpiece. I was just letting it run, but then a 6" long piece of the swarf wrapped around the spindle, and almost crashed me.
I’m having to babysit the machine, and pause every 5 passes or so to pull the strands away from the work. Should I be using a different setting (faster, slower, shallower, etc.) to avoid this, or is it just a “feature” of this material.
For the record, wood and foam have been producing chips as I’d expect, and the cutter has less than an hour on it, so I don’t think there are problems there.
