ABSTRACT:
In an electro-discharge machining method for progressively conducting precise machining through relative approach movements between an electro-discharge machining electrode and a workpiece in the horizontal direction substantially perpendicular to a direction in which said electrode is opposed to said workpiece, the method comprises a step of dividing a movement region of said relative approach movements into a plurality of sections within the horizontal plane and a step of selecting trajectories of said relative approach movements for the respective sections for successively and progressively achieving the machining.
