1、 - 1 - 论题题名：电火花加工的现状与前景 摘 要摘 要 目前，在电火花加工基础理论研究领域，由于放电过程本身的复杂性、随机 性以及研究手段缺乏创新性， 迄今尚未取得突破性进展。但在加工工艺和控制 理论研究领域，由于研究成果可直接应用于生产实践，因此已成为目前电火花成 形加工技术研究中较为活跃的领域，其研究热点主要集中在高效加工技术、高精 密 加工技术(如镜面加工技术)、低损耗加工技术、微细加工技术、非导电材料 加工技术、电火花表面处理技 术、智能控制技术(如人工神经网络技术、模糊控 制技术、专家系统等)以及操作安全、环境保护等方面。 在工艺设备开发方面， 目前的新型电火花成形加工机床在加

2、工功能、加工精度、自动化程度、可靠性等 方 面已全面改善，许多机床已具备了在线检测、智能控制、模块化等功能，已 不再是传统意义上的特种加工机床，而更像切削加工中的数控机床甚至加工中 心。 关键词：技术；产业；发展；前景 - 1 - Abstract The electric spark forming processing technology development status of electric spark machining at present, in the field of fundamental research, since the discharge process c
