Abstract

PURPOSE:To form a desired relief pattern on a curved surface by means of electrical discharge machining process by electrically discharging between a metallic flat plate base mold cut with a plane developing pattern having ruggedness corresponding to desired relief pattern and a workpiece to be machined. CONSTITUTION:When teeth 5a, 5b are formed on the outer periphery of a workpiece 2 to be machined, a metallic rack member 3 having projections 4a, 4b obtained by developing the shape of the teeth 5 on a plane is prepared, and there is electrically discharged between the workpiece 2 and the rack member 3. When the workpiece 2 is moved in the direction B while rotating the workpiece 2 in the direction A, the teeth 5a, 5b are sequentially formed. When a raised character A is formed on the peripheral surface of a workpiece 21 of cylindrical shape, there is electrically discharged between the metallic flat plate base mold 20 formed in recess with the character A and the workpiece 21 to then move the workpiece 21 in the direction D while rotating it in the direction C.
