| Abstract: | Aiming at high strength steel, a series of orthogonal turn-milling tool wear experiment had been done by adopting TiN coated carbide tool. Taylor equations of tool life T-(v_c,f_a,f_z) in orthogonal turn-milling high strength steel are analyzed and erected. The relation between tool life and cutting regime is studied. At the same time the mechanism of tool wear and tool fracture in turn-milling high strength steel is studied to show that the main reasons of tool wear are fatigue-delaminating wear of tool surface material, cutting edge micro-collapse and elements chemistry reaction wear between tool material and medium all around under high cutting temperature. |
