摘　　要：本文通过正交试验研究了PCD刀具车削钛合金Ti-6A l-4V时,动态切削力和表面粗糙度随切削用量的变化规律,并分别以Ra、Rz为指标进行了方差分析。试验结果表明:x向和y向动态切削力随切削用量的变化很小,而z向相对较大。动态切削力随进给量和切削深度的增加而增加,其中在切削深度为0.1 mm的情况下,切削力出现了较大的波动。进给量和切削深度均对Ra、Rz有显著影响,其中进给量对Ra影响较大,切削深度对Rz影响较大。In this paper,orthogonal experiment was done to study the cutting performances of PCD tools when cutting Ti-6Al-4V.The regulation of dynamic cutting force and surface roughness were analyzed with different cutting parameters.Index Ra,Rz were also analyzed respectively by method of variance analysis.The results showed that dynamic cutting force Fz varied much compared with dynamic cutting force Fx and Fy.Dynamic cutting force increased with feed and depth of cut,especially when depth of cut was 0.1 mm.Feed a...
