ABSTRACT:
A fabricating machine in which a machining tool or electrode is used to machine a workpiece and is subsequently moved relative to the workpiece in a direction perpendicular to the tool or the electrode machining direction in a circular motion relative to the workpiece for machining the workpiece while gradually expanding or reducing the moving path of the tool or the electrode in a predetermined amount including discriminating means for determining whether or not the electrode is in a machining enabling state or in a machining disabling state for the workpiece, and tool or electrode moving path deciding means for expanding or reducing the moving path of the tool or the electrode in a predetermined relationship. The electrode speed can also be varied in response to the detected machining state. Thus, a preferable finish machining can be performed with a sufficient machining efficiency by optimally controlling the increased machining margin and speed of the electrode in response to the machining capacity when the electrode is moved in a circular motion.
