采用红外热像仪测量微细铣削加工航空铝合金材料中的切削温度。分析微刀具、工件及切屑的温度场分布规律;研究进给速度、主轴转速、背吃刀量对切削温度的影响。研究结果表明微细铣削加工中切削温度较低,最高切削温度出现在微刀具与工件的接触区域。进给速度对切削温度影响较大。该试验结果可用于微细铣削加工参数优化,也可为提高工件表面加工质量、合理设计与使用刀具提供理论依据。
Measurement of cutting temperature in microalloyed aviation aluminum alloy by infrared thermography. Analysis of micro-cutting tools, workpiece and chip temperature distribution of the law; study feed speed, spindle speed, the amount of back eating cutting temperature. The results show that the cutting temperature in micro-milling is low, and the highest cutting temperature appears in the contact area between micro-cutting tool and workpiece. Feed speed has a great influence on the cutting temperature. The test results can be used to optimize the parameters of micro-milling, and also provide a theoretical basis for improving the surface processing quality and designing and using the cutting tools reasonably.
