摘　　要：为了了解切削参数影响碳钢微量润滑切削温度的规律,通过45钢的车削实验,利用自然热电偶测温,探明在干切削、传统浇注润滑和微量润滑条件下,不同切削参数对切削温度的影响及原因。实验结果表明:MQL切削温度随切削参数增大而上升,切削速度对MQL温度影响最大,切削深度影响最小;在低切削速度时,MQL冷却效果优于传统浇注润滑,在中、高速时,MQL冷却效果比浇注润滑差;MQL冷却能力随切削速度和进给量增大而减弱,不随切削深度而变化。In order to understand effect of cutting parameters on cutting temperature of minimal quantity lubrication（MQL） of carbon steel,there was a 45 steel turning experiments. In the experiments,natural thermocouple was used to measure cutting temperature by different cutting parameters in conditions of dry cutting,MQL or conventional casting lubrication,and the laws and reasons were learned. The results show that MQL cutting temperature increases with the rise of cutting parameters,cutting speed has the greatest impact on MQL cutting temperature and cutting depth has the minimal impact; MQL cooling effect is better than traditional casting lubrication at low cutting speed,but it is worse in the middle or high cutting speed; MQL cooling capacity is weaken with increasing cutting speed or feed rate,not with cutting depth.
