摘要：Ultra-precision machining of tungsten carbide (YG10) can be realized under the combined assistance of laser heating and two-dimensional ultrasonic vibration. In order to study the wear mechanism of PCBN cutting tool and its influence on cutting process, the cutting tool wear condition and the evolution process of flank wear are observed, and the wear mechanism of PCBN cutting tools is analyzed under the combined effects of laser and ultrasonic vibration. Compared with the traditional cutting, the laser-assisted cutting, the two-dimensional ultrasonic vibration cutting, it is studied that the effect of tool wear on the machining precision, machining quality, and cutting force with the change in length of cut in laser heating and two-dimensional ultrasound composite-assisted cutting (LUAC) and the tool wear characteristics are analyzed under the special coupled thermo-force. The research results show that the LUAC can effectively alleviate tool wear, improve dimensional precision and surface quality, and reduce cutting forces.
