Electrical discharge machining(EDM)is widely used because it can efficiently and precisely machine parts of conductive materials that are difficult to machine.Among them,EDM milling is one of the main processing methods for micro finishing of parts with complex shapes.In this paper,in order to meet the requirements for efficient and precise milling of micro structures of key components in the field of military and civil integration,such as aerospace,automobile,etc.,a precision milling method based on CNC EDM machine tools using simple round electrodes is proposed.The method mainly uses segmented milling and reverse superposition compensation to learn and master the milling rules,so as to achieve low-cost,precise and efficient milling of parts.
