摘要 钛合金型腔圆角加工容易发生切削负载增大和颤振等现象,导致圆角表面质量较差,难以实现钛合金高效加工。通过钛合金型腔圆角铣削试验,基于铣削力和圆角表面质量检测,分析内圆角铣削特征和原理,并优化铣削参数。试验表明:采用小切削宽度的高速加工,可实现钛合金内圆角的高效加工;在Vc=90m/min,ft=0.06mm/t,ap=20mm,ae=1mm切削参数组合下,切削力相对较小,加工效率高,切削表面质量高。 For corner milling in titanium alloy cavity,the cutting load increase and chatter are easy to occur,resulting in poor quality of the corner surface,and it is difficult to achieve high-efficiency processing of the titanium alloy.The milling experiment of titanium alloy cavity is carried out,the milling characteristics and principle of inner corner milling are analyzed,and the milling parameters are optimized based on the test of the milling force and the surface quality.The results show that high performance machining of corner processing titanium alloy can be resolved by the high speed machining with small cutting width,and the cutting force is relatively small,the quality of surface is high in Vc=90m/min,ft=0.06mm/t,ap=20mm,ae=1mm.
