In this report, the effects of ultrasonic gear cutting by using the MICRON hobbing machine were investigated. The experiments were performed by a gear blank of ultrasonic vibration, which is chucked to the main spindle and conventional motion hob. The frequency is 29 400 c/s constant, amplitude variable and three kinds of gear blank of M=0.75 Z=22 are used, i.e., those of aluminum, brass and mild steel. The results were as follows ; 1) At first, it was found that the revolving gear blank can be vibrated by using the carbon brush and brass slip ring without any spark trouble etc. 2) The type of chip was shear or flow type, but the conventional chip was all tear type. 3) The machined surface was very smooth. 4) After all, it was found is this ultrasonic gear cutting that the heigh frequency impact farce, which caused the work or tool to vibrate, was very important facter in the cutting process.
