PCBN刀具高速切削钛合金切削力和表面质量的研究

Investigation on Cutting Force and Surface Quality of PCBN Tool in High-speed Machining of Titanium Alloy

针对PCBN刀具材料和钛合金Ti6Al4V工件材料的特点,采用单因素试验法,对切削力和已加工表面粗糙度进行研究。通过与其它刀具材料作对比,证明了PCBN在高速、低进给量、低背吃刀量下切削钛合金可以得到较平稳的切削力和较低的工件已加工表面粗糙度。

Based on the characteristic of PCBN tool material and titanium alloy Ti6A14V workpiece, single -factor experimentation will be made to research on cutting force and machined surface roughness. It is proved that stabile cutting force and lower surface roughness are gained in machining titanium alloy Ti6A14V used PCBN compared with other tool ma- terials.
