锗的高压Ge-II相具有类似的金属切削特性。在单点金刚石车削中，为了最大限度地提高锗的高相变区，易于实现延性切削。采用单因素试验方法模拟不同加工工艺参数和刀具几何参数下的超精密车削过程。通过模拟结果中高压相变区面积的计算以及切削温度变化规律的描述，得到了不同工艺参数和刀具几何参数对相变区演化的影响规律，为车削试验参数的选择提供了有益的参考。
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.
