Highefficiency milling speed changes rules
· Stepping from the world of standard milling to highefficiency milling (HEM) can change just about everything. HEM's lower radial depth of cut (RDOC) and a higher axial depth of cut (ADOC) create consistent wear across the end mill cutting edge, generate less heat, and lessen the chance of tool failure. Machines can sustain less stress and tooling can last much longer. Two basic concepts ...
