All I have learned so far is HDPE prefers convention milling to climb, and it seems to cut the same at any feed rate and spindle speed….Single flute up cut bits are nice, down cut melts the plastic. Cutting 6.7mm per pass, about .1-.2 into the wood, spindle speed as low as possible and 2.5mm/s is okay, so now faster spindle and faster feed rate and see what this can do.
