中文摘要：

为了改善切削加工过程中切削温度高,刀具与工件发生粘连现象等不良影响,在切削中加入冷却因素,以达到较好的切削效果。针对较为常见的几种冷却方式（低温冷风、高压水射流、冷温冷风雾化射流、切削液）,通过仿真做了一系列对比分析,分析了切屑形态、切屑形成速度、切削力、温度以及工件表面应力在不同冷却切削条件下的变化。通过比较发现,冷温冷风雾化射流的冷却效果最好。

英文摘要：

In order to eliminate the adverse effects of high temperature in cutting, and the adhesion of the cutting tool and the workpiece, the cooling factors shall be added to achieve better cutting effect. In this study, the changes of chip shape, chip formation, cutting force, temperature and surface stress in different cooling cutting conditions were analyzed by simulating the common cooling methods （cold air, water jet, cold and warm air atomizing jet, cutting fluid）. The result shows that the cold temperature and cold air atomizing jet is of the best cooling effect.
