电蝕加工是一门年輕的学科。它具有許多独特的优点,并且可以作许多形式的加工,所以一开始就得到人們的重視,并且很快地在工业上应用。近年来,由于工业技术的发展,在加工上提出了許多新的要求,而这些要求正是电蝕加工易于解决或是将可解决的,所以在最近的一个时期里,电蝕加工又得到急速的发展。正因为如此,人們对电蝕加工今后的发展十分关切。捷克斯洛伐克科学技术协会去年九月在布拉格举行了一次“电蝕加工新方向”的会議。这是第一次国际性的电蝕加工会議,参加会議的有中、苏、捷、波、匈、德、英、法、瑞士及西德等 Electric erosion machining is a young discipline. It has many unique advantages and can be processed in many forms, so it got the attention from the very beginning and was quickly applied industrially. In recent years, due to the development of industrial technology, many new requirements have been put forward for processing. These requirements are easy to solve or can be solved by electro-erosion machining. Therefore, in recent period, electric erosion machining has been rapidly developed development of. Because of this, people are very concerned about the future development of EDM. Czechoslovakia Science and Technology Association held a “new direction of electro-erosion machining” meeting in Prague in September last year. This is the first international electro-erosion machining meeting attended by the participants from China, the Soviet Union, Czech Republic, Poland, Hungary, Germany, Britain, France, Switzerland and the West Germany
