Research on an Ultrasonic Cutting Device Based on 0Cr18Ni9

For precision machining of 0Cr18Ni9, a two‐dimensional ultrasonic cutting device is studied, which is composed of an elliptical ultrasonic vibration‐working head and a two‐dimensional high‐power ultrasonic driving system. The working head is designed according to the size of the lathe tool post. The flange is designed in the nodal plane, and the ultrasonic oscillator is fixed in the flange plate, which can reduce the mechanical loss of vibration. The drive system can realize the linkage amplitude and synchronous control of the two arms. The speed of the synchronous frequency tracking is fairly fast, and the precision is satisfactory. The vibration shape of the working head can be arbitrarily set, and the vibration shape is stable. Through the cutting experiments of 0Cr18Ni9, the relationship between the speed of cutting line and the quality of cutting and the relationship between the vibration shape and the cutting quality, tool wear, and chip are all analyzed.
