超声振动切削技术发展简述

A Brief Introduction to the Development of Ultrasonic Vibration Cutting Technology

超声振动切削作为一种特种加工方式,在金属切削、脆性材料与复合材料加工领域中有着广泛的运用。一维超声振动切削和椭圆超声振动切削是超声振动切削加工的两种常见形式,能有效地降低切削力、切削热,并提高刀具寿命和加工表面质量。高速超声振动切削作为一种新方法被提出,打破了前二者的临界切削速度,并在TC4钛合金切削实验中保持了超声振动切削的传统优势,同时实现了200~400 m/min的高速切削,将超声振动切削推入了高速化发展阶段。

As a non-traditional machining method, ultrasonic vibration cutting has been widely applied in the metal cutting,brittle material and composites machining fields. One-dimensional ultrasonic vibration cutting and ultrasonic elliptical vibration cutting are two common types of ultrasonic vibration cutting ,which can effectively reduce the cutting force and cutting heat, enhance the tool life and improve the finishing surface quality. Recently,a new method named high-speed ultrasonic vibration cutting was proposed and it had broken through the ultrasonic vibration cutting critical cutting speed. In the Ti-6A1-4V alloys turning experiment,the cutting speed of high-speed ultrasonic vibration cutting reached 200 to 400 m/min with all the traditional benefits. All of these achievements have led ultrasonic vibration cutting to high speed machining stage.
