Abstract
The high-speed milling experiments on hardened Cr12MoV steel were carried out with ball end milling cutter of different edge parameters. The influences of helix angle and rake angle on tool life and surface roughness were focused on. Meanwhile, the impacts of edge parameters on cutting edge stiffness and flank wear were analyzed on the condition of high-speed milling. It carried out that smaller helix angle and negative rake angle selected during high speed milling can guarantee quality of surface manufactured as well as longer tool life.
