Abstract

PURPOSE:To offer a high performance processing with a finer roughness on the processed surface made in conditions that the fusion time at a discharge point becomes short by controlling the relative moving speed of electrode to a work to be processed in such a way that this speed will become higher in compliance with said shortened fusion time and, thereby, making the major diameter of ellipses of discharge striation twice as large as the minor one or more. CONSTITUTION:A work to be processed 1 is fixed to the table 6 of NC feed control and driven by motors 7, 8 along the X and Y axes. By processing pulses from the pulse souce 10, discharge is applied to the gap between work 1 and electrode 2 which is filled with the working liquid, and processing is carried through with repeated discharge. A relative movement is made between the electrode 2 and work 1 by the electrode 2 rotating at a high speed, and a mark will propagated in a elliptic form. The minor diameter of the ellipse shall be suppressed to half the major one or further by controlling said relative movement through regulation of the rotary speed of the electrode 2 in compliance with the pulse width to control the fusion time at discharge point of the processing pulses fed from the pulse source 10.
