Abstract: The lives of the two CERMETS cutters were investigated when turning 45carbon steel in the same cutting condition. The effect of tool orthogonal clearance on tool life was also researched in this paper. The results of the experiment were indicated as: the cutting performance of Nano TiN modified TiC-based CERMETS cutters was obviously superior to that of ultra-fine Ti(C, N)-based CERMETS cutters. And the length of cutting path of the two cutters was longest with the tool orthogonal clearance of 3-4°.

Abstract: A theoretical model of temperature for electrical discharge machining (EDM) is established. Based on finite element method, the distribution temperature fields of ZL108, YG15 and 45 carbon steel during EDM process are simulated with the aid of ANSYS software. The simulation model provides good effects on the surface quality forecast, parameter regulation and optimization in the process of EDM. Under same experimental conditions, the machining efficiencies of EDM ZL108, YG15 and 45 carbon steel are listed. The machining efficiency of EDM ZL108 or 45 carbon steel is much higher than YG15. The observations of YG15, ZL108 and 45 carbon steel surface micro-patterns after EDM are made by VHX-600 3D digital microscope. Form the experimental results, we can explain why ZL108 and 45 carbon steel are tractable metals, while YG15 is difficult-to-cut metal.
