摘要： A method for detecting and compensating electrode wear of electric discharge machining (EDM) is disclosed, which comprises the steps of: defining a calibration node; calculating a wear length of a tool electrode by an edge-finding algorithm; using the calculated wear length of the tool electrode as a cut compensation for compensating a machining depth of next new tool electrode replacing the previously machined tool electrode; whereas the machining depth is obtained according to the following formula: the machining depth=designed depth of cut+predicted wear of the tool electrode for machining to desire depth−calculated wear length of the previously machined tool electrode+a through hole offset. With the aforesaid method, the wear of an used tool electrode can be detected automatically for compensating the machining depth of an unused tool electrode without ant additional equipment while achieving accurate machining.

摘要： An electrochemical discharge machining device includes a base, a sensor disposed on the base, a shaft rotatably disposed on the base, an electrode disposed at one end of the shaft and contacting with a work piece, an isolating element disposed between the sensor and the shaft, and a control module connected to the sensor. Current flows to the electrode via the shaft to machine the work piece, and the force exerted on the electrode by the work piece is transmitted via the shaft and the isolating element to the sensor converting the force into a signal sent to the control module for raising or lowering the base to maintain contact between the electrode and the work piece. The sensor serves as a detecting mechanism to ensure appropriate contact between the electrode and the work piece.
