钛合金是一种典型的难加工材料,其热传导率低,切削过程温升大而易加剧刀具磨损。本文通过对TC4钛合金的车削试验,研究了在干切削和复合喷雾冷却条件下切削温度随切削速度、切削深度和进给量的变化情况。结果表明:切削温度随着切削速度、切削深度和进给量的增大而增大;采用复合喷雾冷却技术可在TC4钛合金车削过程中取得较好的冷却效果,切削温度明显低于干切削条件下的切削温度。
Titanium is a typical hard-to-process material with low thermal conductivity and large temperature rise during cutting, which can exacerbate tool wear. In this paper, TC4 titanium alloy turning test, under dry and composite spray cooling conditions cutting temperature with the cutting speed, cutting depth and feed changes. The results show that the cutting temperature increases with the increase of cutting speed, depth of cut and feed rate. The cooling effect of TC4 titanium alloy is better than that of dry cutting Cutting temperature under conditions.
