Study on ultrasonic vibration cutting (3rd Report) - Multiple precision cylindrical machining with combining ultrasonic vibration cutting on thrust force direction, and superposition superfinishing process

The objyective of this investigation is an invention of theory and technics on high precision cylindrical machining with combining ultrasonic vibration cutting on thrust force direction, and superposition superfinishing process. In this report, it is analyzed that multiple precision cylindrical machining is possibly achieved with using insensitive vibration cutting mechanism on thrust force direction, and microgroove self control mechanism on superposition superfinishing. The experiments for precision cylindrical machining have be done, after some testinng for deciding a suitable condition on ultrasonic vibration cylindrical terning on thrust force direction, and superposition superfinishing. In the multiple experiments, roundness 0.3μm∼0.6μm, surface roughness 0.1μmRz∼0.2μmRz could be achieved for aluminum alloy, brass and carbon steel. These results indicates that multiple machining system is appropriate for precision cylindrical machining.
