This review discusses the machining of SiCp/Al composite materials, focusing on their unique properties and challenges in processing. SiCp/Al composites are widely used in aerospace and electronics due to their excellent material properties, but their machinability is significantly reduced due to the hard and brittle nature of SiC particles. The review analyzes the processing mechanisms, including turning, milling, drilling, grinding, special machining, and hybrid machining, and summarizes the latest research progress while identifying existing problems. It aims to enhance the machinability of SiCp/Al composites and promote high-quality and efficient processing methods. The machining of SiCp/Al composites presents significant challenges due to the high hardness and brittleness of SiC particles, leading to severe tool wear and poor surface quality. The review discusses various machining techniques, including turning, milling, drilling, and grinding, and highlights the impact of process parameters on tool wear, surface roughness, and cutting force. It also explores special machining techniques such as EDM/WEDM, electrochemical jet machining, and laser processing, which are suitable for processing SiCp/Al composites due to their non-contact nature and ability to handle hard materials. The review emphasizes the importance of optimizing machining parameters to improve surface quality and tool life. It discusses the effects of cutting speed, feed rate, depth of cut, and tool geometry on the machining process. Additionally, it highlights the role of advanced modeling and simulation techniques in predicting tool wear and optimizing machining parameters. The review concludes that further research is needed to develop more efficient and precise machining methods for SiCp/Al composites, ensuring high-quality and efficient processing.This review discusses the machining of SiCp/Al composite materials, focusing on their unique properties and challenges in processing.
