PCD刀具加工SiC颗粒增强铝基复合材料的合理切削速度

The Optimum Velocity of Cutting SiC p Reinforced Aluminium Matrix Composite with PCD Tool

通过用扫描电镜等方式检测ＰＣＤ刀具的性能，并与天然金刚石的相关参数进行比较，阐明了ＰＣＤ刀具的优异性能。通过ＰＣＤ刀具对碳化硅高比强颗粒增强铝基复合材料的试验，考察了切削速度对切削力、切削温度、刀具耐用度和切削长度的影响，总结出高硅铝基复合材料切削中的合理切削速度。指出，在一定的切削条件下，当切削速度Ｖ＝３０～４０ｍ／ｍｉｎ时，可获得良好的综合效益。

The high performance of PCD tool were expounded by testing the property of PCD tool with SEM and comparison with natural diamond Base on the test of PCD tool cutting high strength SiC p reinforced aluminum matrix composite,the influence of cutting speed on cutting force,surface roughness, tool life and the cutting length were discussed, and the optimum cutting speed in this course was summarized.It is shown that the best total efficiency can be obtained when the optimum velocity is from 30 to 40 meters per minute
