| Abstract: | Based on the finite element software,a 3-D finite element model(FEM)of metal cutting was built.The cutting process of new-style Ti(C,N)-based nano-cermet cutter was simulated subsequently.Cutting force and toolwear were obtained as well as the distribution law of temperature.The optimum rake angle was calculated when cutting normalized 45# steel with Ti(C,N)-based nano-cermet cutter.The validity of the simulation results was demonstrated by a series of cutting tests.The simulation and experimental results show that 3-D simulation can disclose the cutting status more objectively than 2-D simulation,and it puts up a more effective method for research of metal cutting theory and development of new cutters. |
