摘要

Carbon fiber-reinforced polyetheretherketone (CFR-PEEK) composites have been increasingly used in aerospace, biomedicine, and other fields because of their excellent mechanical properties and outstanding corrosion resistance. Ultrasonic vibration cutting offers low cutting force, high material removal rate, and good surface quality. In this study, a two-dimensional CFR-PEEK material model with randomly distributed fibers was developed, and ultrasonic vibration cutting simulations and experiments were conducted. Four cutting speeds, namely feed rate of 0.1 mm/r, cutting depth of 0.1 mm, and cutting speeds of vc = 20 m/min, vc = 40 m/min, vc = 60 m/min, and vc = 80 m/min, were selected for the test. As the cutting speed increases, the cutting force and surface roughness also increase. Ultrasonic vibration also helps generate curved chips and reduce heat accumulation in the cutting area. The cutting speed of 20 m/min, the depth of cut of 0.1 mm, and the feed rates of 0.05 mm/r, 0.1 mm/r, 0.15 mm/r, and 0.2 mm/r were selected for the test. It was found that the micro-texture generated by ultrasonic vibration can reduce the coefficient of friction and improve anti-wear performance.
