Abstract: For the machinability difficulty of GH4169 Ni-based superalloy and 5A06 Al-Mg alloy as well as the high demands of machined surface quality and machining precision, the ultrasonic vibration assisted turning machining system was designed utilizing the method of ultrasonic vibration, which proceeded with cutting principle and machining technology. The contrast test was conducted to compare ultrasonic vibration assisted turning with conventional turning for these two alloy materials. The results indicate that the technological parameters have obvious effect on the surface roughness, surface topography and chip morphology of machined workpiece when ultrasonic vibration assisted turning of Ni-based superalloy and Al-Mg alloy is conducted. Choosing reasonable technological parameters can promote efficiently the processing quality, and enable the machining effects of ultrasonic vibration assisted turning to be superior to that of conventional turning.

Key words: ultrasonic vibration assisted turning, technological parameter, surface roughness, surface topography, chip morphology
