Forgot to answer this message that falled into the spam folder for some reason. It's going to be PVC so it's in the thermoplastic category. > An LCNC based process control would make such operations easier by having > machine profiles for each mold and material combination's heat/cool cycle. > > On this list we've seen some non-machining uses for LCNC, like an > automated induction heat treating system for engine camshafts.
