Mad Profs calc are to run at 50 to 60mm/sec. What would you recommend with a 6mm twin straight fluted bit. Also would it be possible to do this in say 3 passes? Still not sure what the VFD readout at 3000 means. The readout can go to 4000 when up full. The max spindle speed is 14,000rpm according to the spindle spec.
I agree that speeds and feeds will have a big influence on tool life. Obviously I am looking for the best running conditions for longest tool life on this type of mdf
