搭接成型盘铣刀铣削减小薄壁类零件变形和振动的方法

Method of Using Lapped Jiont Profile Disk Milling Cutter to Decrease Deformation and Vibration of Thin Wall Part

薄壁件由于强度低,在铣削中由于受到切削力而易发生变形。同时,由于薄壁件刚性差,加工时容易振动而影响加工表面的粗糙度。本文论述了采用可转位盘铣刀通过搭接成型、进一步细分精铣,一次走刀完成普通精铣和修光精铣、探索最优切削参数等方法减小薄壁件加工中的切削力和振动,提高加工质量和效率,并用加工实例证明了该方法的有效性。

Thin wall part is easy to deforming when it is milled,because of its low strength.What is more,As its low stiffness,thin wall part is more likely to vibrate.This will decrease machined surface roughness.This paper presents that using indexable disk milling cutter,further subdivision of finish milling,one time to complete the ordinary finish milling and wiper finish milling,exploring the optimal cutting parameters can decrease cutting force and vibration of thin wall part,improve processing quality and efficiency.Furthermore,a processing example is utilized to demonstrated the validity of those method.
