Abstract

The main purpose of this paper is to study the carbide tip’s surface temperature and the cutting forces of milling stainless steel with chamfered main cutting sharp worn tools. The carbide tip’s mounting in the tool holder are ground to a wear depth that is measured by a toolmaker microscope and a new cutting temperature model incorporating tool wear factor and using the variations of shear and friction plane areas occurring in tool worn situations are presented in this paper. The tool tip and cutting edges are treated as a series of elementary cutting tips. The forces and frictional heat generated on elementary cutting tools are calculated by using the measured cutting forces and the oblique cutting analysis. The carbide tip’s temperature distribution is solved by finite element analysis (FEM) method.
