SiCp/Al复合材料是一种典型的难加工的材料,由于其基体中颗粒增强导致常规切削中加工质量差、切削阻力高、加工损伤高,机械加工性差,常规切削已不能满足加工要求.通过切削仿真,对比分析常规与超声振动辅助切削条件下复合材料的切削过程、SiC颗粒的损伤特性、工件的表面形貌与亚表面损伤.结果表明,相比于常规切削,超声振动辅助切削可以提高复合材料的表面完整性,减少复合材料的亚表面损伤,并且能够提高工件的表面质量.
Finite element analysis of cutting process and surface formation of SiCp/Al composites under conventional and ultrasonic vibration assisted conditions
SiCp/Al composite is a typical difficult-to-machine material.Due to the presence of particle reinforcement in its matrix,it leads to poor machining quality,high cutting resistance,high machining damage and poor machinability under conventional cutting conditions.Conventional cutting can not meet the processing requirements.Through cutting simulation,the cutting process of composite materials,the damage characteristics of SiC particles,the surface morphology and subsurface damage of workpieces under conventional and ultrasonic vibration assisted cutting conditions are compared and analyzed.The results show that compared with conventional cutting,ultrasonic vibration assisted cutting can improve the surface integrity of the composite material,reduce the subsurface damage of the composite material,and improve the surface quality of the workpiece.
