Abstract

Abstract In order to optimize the geometric parameters of cutting edge for finishing machining of Fe-Cr-Ni stainless steel, a 2D finite element (FE) model of orthogonal cutting has been built with FE software AdvantEdge. The optimized methodology of cutting edge geometric parameters has been proposed based on simulated results. Then, the geometric parameters of cutting edge have been optimized based on a comprehensive criterion combining chip deformation coefficient and tool stress, where chip deformation coefficient indirectly determines the surface roughness and tool stress determines tool wear, which affect the dimensional precision of parts. The scope of rake angle is from 10° to 20°, and the scope of cutting edge radius is from 5 to 15 μm in the optimization process. The optimal rake angle for finishing machining Fe-Cr-Ni stainless steel is 16°, and the optimal cutting edge radius is 7 μm with a given relief angle of 7°.
