摘要

摘要: 电火花线切割是精密与特种加工重要组成部分,影响线切割加工精度的因素很多,而各种因素对加工精度的影响最终都以电极丝动态形式表现出来。传统电极丝稳态控制方法是降低走丝速度,但同时也降低了加工效率,所以旨在解决高精度和低效率问题的电极丝动态特性一直是全世界学者研究的焦点。本文中分3个方面介绍了电火花线切割电极丝动态特性研究现状:振动模型、热模型和稳态控制,并对现有研究中存在的主要问题及研究方向进行了阐述。

Abstract: The wire-cut electrical discharge machining(WEDM) is an important part of precision and special machining.There are many factors of influence on the WEDM precision,which exhibit themselves in the form of the dynamic characteristics of wire electrode.The traditional wire electrode stability control method reduces not only the wire-moving speed but also the machining precision.So the problem lies in understanding the dynamic characteristics of electrode wire.This paper presents a review on the dynamic characteristics of WEDM electrode wire from three perspectives： vibration model,thermal model and stability control.It also points out the existing issues and research trends.
