ABSTRACT:
To obtain high machining speed and machining accuracy in three-dimensional machining by using of an electrode of simple shape. Applying voltage between an electrode of simple shape and a workpiece, performing three-dimensional control by an NC control while synthesizing a feed of a Z-axis direction for correcting longitudinal consumed amount of an electrode with an X-Y plane feed, storing amount equivalent to an X-Y moving distance in an X-Y plane corresponding to correcting moving amount of the Z-axis direction in an electrical discharge machining method for machining a desired three-dimensional shape and performing a feed of correcting moving amount in the Z-axis direction each time a moving distance in the X-Y plane on a moving locus during machining reaches the above stored amount.
