Study on Laser-assisted Machining of Aluminum-based Silicon Carbide

In order to explore the feasibility of laser-assisted machining (LAM) in the field of metal matrix composites (MMCs), an orthogonal precision micro-cutting experiment of 45% volume fraction aluminum-based silicon carbide (SiCp/Al) was carried out, and the experimental results were analyzed and discussed. The experimental results show that laser-assisted processing can improve the processing characteristics of SiCp/Al materials. Under the appropriate laser power, the laser assisted processing technology can effectively improve the surface roughness of the workpiece to be processed, obtaining a high-quality surface finish, and increase the tool wear resistance to a certain extent at the same time. Laser assisted machining technology can be applied to the processing of metal matrix composites.
