研究了用陶瓷作刀具材料高速车削时,倒棱的角度和切削速度对切向切削力,轴向切削力和径向切削力的影响。并指出了适合这种加工的最佳倒棱角的角度范围,三个切削分力随着切削速度的增加而下降,其中,不同角度的倒棱还会引起切削力的明显差别。本文简略地探讨了高速车削问题,并解释了它的范围。 The effect of chamfering angle and cutting speed on tangential cutting force, axial cutting force and radial cutting force was studied when using ceramic as tool material for high speed turning. The optimal chamfer angle range for this kind of machining is pointed out. The three cutting force components decrease with the increase of cutting speed, and chamfering at different angles can also cause significant difference of cutting force. This article briefly discusses the high-speed turning problem and explains its scope.
