Among the various types of metal matrix composites, SiC particle-reinforced aluminum matrix composites (SiC_p/Al) are finding increasing applications in many industrial fields such as aerospace, automotive, and electronics. However, SiC_p/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 SiC_p/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 SiC_p/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 SiC_p/Al composites using various processing technologies but also establishes optimization parameters as reference of industry applications.

SiC颗粒增强铝基复合材料常规加工和非常规加工的综述

在各种类型的金属基复合材料中，SiC颗粒增强铝基复合材料（SiC _p / Al）在许多工业领域（例如航空航天，汽车和电子领域）的应用日益广泛。但是，由于SiC _p / Al复合材料由于坚硬的陶瓷增强材料而被认为是难以切割的材料，会通过增加切削刀具的磨损，切削力等而导致严重的切削性能下降。为提高SiC _p / Al复合材料的切削性能，已经采用了包括常规和非常规机加工工艺在内的许多技术。这项研究的目的是评估SiC _p的加工性能/ Al复合材料，使用常规加工（例如车削，铣削，钻孔和磨削），以及使用非常规加工（例如放电加工（EDM），粉末混合EDM，线切割EDM，电化学加工和新开发的高效加工技术），例如，喷砂腐蚀电弧加工。这项研究不仅提供了使用各种加工技术对SiC _p / Al复合材料进行机械加工的概述，而且还建立了优化参数作为行业应用的参考。
