Simulation Analysis of Influencing Factors of High Pressure Phase Transformation in Single Crystal Germanium Ductile Cutting

Abstract

Abstract The high-pressure phase Ge-II of germanium has similar metal cutting characteristics. In single-point diamond turning, in order to maximize the high phase transition zone of germanium, that is easily to make ductile cutting realized. The single factor test method is used to simulate the ultra-precision turning process under different machining process parameters and tool geometric parameters. Through the calculation of the area of the high-pressure phase change zone in the simulation results and the description of the cutting temperature change law, the influence law of different process parameters and tool geometry parameters on the evolution of the phase change zone is obtained, which provides a useful reference for the choice of turning test parameters.
