ABSTRACT:
The method of abrasion forming friable material such as carbon blocks to form electrical discharge machining electrodes therefrom comprising the steps of moving a master model, having an abrasive surface which is a mirror image of a desired form to be abrasion machined in the friable material, which surface is related in size to the desired form to be machined by an additional movement to be imparted to the master model, toward the friable material with the abrasive surface of the master model and workpiece in engagement while imparting the additional relative motion between the master model and workpiece, which additional relative motion is in all directions in a plane perpendicular to the direction of movement of the master model and workpiece and flushing between the master model and workpiece to prevent build up of abraded particles of the workpiece on the master model.
