摘　　要：针对传统精密孔铰削加工存在的生产效率低、孔的表面质量差、刀具寿命短、废品率高等问题,研究了振动铰削过程的运动学特性,计算振动铰削的断屑条件,分析振动铰削抑制积屑瘤形成和改善孔表面质量的机理。In order to solve the problems of conventional reaming process for precision holes, such as low productivity, poor surface finish of the hole, short tool life, high reject rate and so on, the kinematics prop- erties of vibration reaming process are studied. The chip-breaking conditions of vibration reaming is calcu- lated. The mechanisms of suppressing the formation of built-up edge and improving the surface finish of vibra- tion reaming are analyzed.
