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。

Abstract: | 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 tempera-ture 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 im-pact on MQL cutting temperature and cutting depth has the minimal impact;MQL cooling effect is better than traditional casting lubri-cation 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 . |
