摘要

Among the various types of metal matrix composites,SiC particle-reinforced aluminum matrix composites (SiCp/Al) are finding increasing applications in many industrial fields such as aerospace,automotive,and electronics.However,SiCp/Al composites are considered as difficult-to-cut materials due to the hard ceramic reinforcement,which causes severe machinability degradation by increasing cutting tool wear,cutting force,etc.To improve the machinability of SiCp/Al composites,many techniques including conventional and nonconventional machining processes have been employed.The purpose of this study is to evaluate the machining performance of SiCp/Al composites using conventional machining,i.e.,turning,milling,drilling,and grinding,and using nonconventional machining,namely electrical discharge machining (EDM),powder mixed EDM,wire EDM,electrochemical machining,and newly developed high-efficiency machining technologies,e.g.,blasting erosion arc machining.This research not only presents an overview of the machining aspects of SiCp/Al composites using various processing technologies but also establishes optimization parameters as reference of industry applications.
