Metal cutting is one of the main processing methods and the important processing technologies in modern industrial production and material preparation. There are currently Wire cutting, Gas cutting,Laser cutting and a variety of other conventional and special metal cutting equipments on the market,but those equipments have poor cutting accuracy and surface quality, heat deformation of the workpiece,equipment cost does not match process requirements and other questions. Especially in large thick metal wire cutting,incision prone to tilt. All of the factors constrain the further development and applications of metal cutting technology. In this paper, based on the principle of electrochemical machining, combined with modern CNC technology, we proposed a new method of metal cutting——Metal Electrochemical Fast Wire cutting technology.
