通过TC4铣削加工时的铣削力试验,研究了干切削时和有氮气介质铣削时影响铣削力大小的几个因素,为提高金属去除率优化了切削参数。同时通过刀具磨损试验,对上述两种铣削方式,比较了在不同的切削速度下铣削时铣刀后刀面的磨损,证实了以氮气为切削介质能够大大地改善刀具的磨损状况和提高刀具的寿命。
Through the milling force test during TC4 milling, several factors affecting the milling force during dry cutting and nitrogen milling are studied, and the cutting parameters are optimized to improve the metal removal rate. At the same time, through the tool wear test, we compared the wear of the cutter flank when milling with different cutting speeds on the above two kinds of milling methods. It was confirmed that using nitrogen as the cutting medium can greatly improve the wear condition and improve the tool life.
