【 摘 要 】

In the manufacturing process of complex components we use unconventional or progressive machining methods which can efficiently and with great precision achieve the desired result. We are talking about electro discharge/erosive machining. From an economic perspective, these technologies are used in manufacturing of high precision and complex parts, where it is necessary to achieve accuracy to the thousandth of a millimetre with the machined surface roughness Ra = 0.1 m. These technologies can be used to machine all conductive materials and materials that are difficult to machine by conventional methods, such as sintered carbide and hardened steel. Most commonly used progressive machining methods are sinker EDM and wire EDM. [2]
