Abstract
Nine kinds of carbide nose radius worn tools were used in turning of high-strength carbon-fibre reinforced plastics (CFRP) materials to study the cutting temperature of tip’s surface. A new cutting temperature model using the variations of shear and friction plane areas occurring in tool nose wear situations are presented in this paper. The frictional forces and heat generated in the cutting process are calculated by using the measured cutting forces and the theoretical cutting analysis. The heat partition factor between the tip and chip is solved by using the inverse heat transfer analysis, which utilises temperature on the K type carbide tip’s surface measured by infrared as the input. The tip’s surface temperature is determined by finite element analysis (FEA) and compared with temperatures obtained from experimental measurements. Good agreement demonstrates the proposed model. 15 refs.
