Abstract
Due to the occurrences of debris, the ability of micro-EDM to produce precise dimension is degraded, hence positioning display indicator of micro-EDM machine is not accurately measure the real dimension. Therefore, imprecise workpiece dimension is happen. In order to overcome this problem, in this paper, the use of discharge pulse counting methods to correct this error is introduced. The dimension error from micro-EDM processes by using discharge pulse counting method is much smaller than when using the positioning display indicator of micro-EDM machine. Hence, by using discharge pulse counting method, high precision machining can be achieved.
