Study on Ultrasonic Assisted Laser under Liquid Processing Platform

Abstract

On the basis of laser-ultrasonic machining and water assisted laser combined machining methods a composite processing method of ultrasonic assisted laser under liquid is proposed. As the key of new technology, its experimental device of combined processing is designed. The device mainly consists of laser processing machine, ultrasonic vibration system (ultrasonic generator and transducer), tank and the water circulation system, fixture of specimen. By Using of finite element method nature frequency of tank with two fixtures of specimen is solved under the condition of combined processing. Analysis results show that the main device parts would work reliably under the vibration of transducer. Physical experiment under liquid proved this platform in water could transmit ultrasonic vibration to specimen and the new combined processing is promising.
