<p>PROBLEM TO BE SOLVED: To provide a discharge processing method which suppresses adhesion of processed waste to a finished part.SOLUTION: A discharge processing method uses a discharge processing machine provided with a wire electrode (190), processes a rod-like to-be-processed object (100) having a tip part (101) and a connection part (102) connected continuously to the tip part (101) to obtain a processed body (130) having a finished part (121) and a shank (122) connected continuously to the finished part (121) and includes a step (S2) of processing the connection part (102) into a shape in which the cross sectional area increases continuously as separated from the tip part (102), a step (S3) of finishing the tip part (101) to form a finished part (121) and a step (S4) of subjecting the connection part (102) to discharge processing to form the shank.</p> |
