摘　　要：通过DEFORM有限元仿真软件分析切削参数和刀具参数对单晶锗微细切削温度的影响情况,并采用单因素变量法进行有限元仿真分析。研究结果表明:主轴转速越大,最高切削温度越小;进给速度越大,切削温度越大;切削深度越大,最高切削温度越大;刀具前角增大,切削温度减小;刀具后角增大,切削温度无显著下降;刀尖圆弧半径增大,最高切削温度有所上升。选取主轴转速3000r/min、进给速度12mm/min、切削深度3μm以及刀尖圆弧半径为1mm,设置刀具前角为-10°和后角为20°,可有效降低单晶锗微细切削温度,从而提高单晶锗的加工精度。In this paper,the finite element simulation software DEFORM is used to analyze the influence of cutting parameters and tool parameters on the micro cutting temperature of single crystal germanium.The results show that the higher the spindle speed,the lower the maximum cutting temperature;the higher the feed rate,the greater the cutting temperature;the greater the cutting depth,the higher the maximum cutting temperature;the larger the rake angle,the smaller the cutting temperature;when the flank angle is increased,the cutting temperature does not drop sharply;when the tip radius is increased,the maximum cutting temperature increases.When the spindle speed is 3000 r/min,the feed rate is 12 mm/min,the cutting depth is 3μm,the tip radius is 1 mm,the tool rake angle is-10°and the flank angle is 20°,the micro cutting temperature of single crystal germanium can be effectively reduced,so as to improve the machining accuracy of single crystal germanium.
