Single Crystal Germanium

Abstract: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 3000r/min，the feed rate is 12mm/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.
