Ulianov Chuvash State University, 15 Moskovsky Prospekt, Cheboksary, 428015, Russian Federation Abstract Electric discharge machining (EDM) is by far the most intensively developing industry in the field of metalworking. This is most clearly seen in the instrumental sphere. The EEE principle is applied on machines of various configurations. The load on the equipment of the erosion group increases. Moreover, electrodes for piercing machines and second-order tools are often made on wire EEE machines. Production is faced with the problem of opening up bottlenecks. With the development of computer technologies and methods of CNC processing, new possibilities for the processing of parts by the erosion method appear. Custom trajectory erosion milling allows the production of parts from difficult-to-machine materials without the use of traditional surface- copying electrodes. The result is the freeing up of equipment and engineering resources, thereby increasing production efficiency. This paper describes the experience of introducing the technology of electrical discharge milling at JSC “Cheboksary Electrical Apparatus Plant” (JSC ChEAZ) Keywords Multiaxis machining, EDM, wire cutting, electrodes, electrode orbital motion, EDM, contouring, control program.
