Abstract

A system of detection and transmission of ultrasonic machining incorporating a motor, an ultrasonic horn and a cutting tool mainly includes a detector, a vibrator and a transmitter. The vibrator is made of piezoelectric material and is used to create ultrasonic vibrations, and the detector made of piezoelectric material is used to physically detect the vibrations. The transmitter includes a fixed ring connected with the ultrasonic horn to remain fixed and a rotary ring connected with the cutting tool to conduct rotary manufacturing. A plurality of balls are located between the fixed ring and the rotary ring. By means of the above design, the transmitter is able to effectively transmit the displacement to the cutting tool vertically, and the accuracy of machining is ensured via the detector establishing a control system of feedback.
