摘要

SiCp/Al composite materials are extensively utilized in aerospace, electronic equipment, and military fields due to their high hardness, wear resistance, and corrosion resistance. However, the tool wear is significant when processed by traditional milling methods, and the surface quality fails to meet the application requirements. Laser energy field–assisted machining and ultrasonic vibration machining have shown promising results in difficult-to-machine applications. Therefore, this study proposes integration of the two machining methods, simulating and verifying the laser thermal field, and experimentally machining SiCp/Al materials under the laser-ultrasonic composite field to investigate their surface morphology and cutting characteristics. As the laser energy density increases, the peak temperature and oxide layer thickness on the workpiece surface increase continuously, although the rate of increase gradually slows down; under identical conditions, the milling force under laser-assisted conditions is reduced by 17.94–31.60%, and the cutting force of composite cutting is reduced by 34.72–39.97%; both laser and ultrasonic amplitudes reduce the surface roughness, with the maximum reduction being 37.7% and 22.2%, respectively; compared with ordinary milling, the surface morphology is significantly improved under laser-ultrasonic composite field milling.
