Abstract
An electromachining apparatus includes a mandrel for supporting a workpiece next to a cutter mounted on an arbor. The workpiece is powered as an anode and the cutter is powered as a cathode, and a coolant is circulated therebetween. The cutter is rotated and plunge twisted into the workpiece to form a twisted slot therein, with adjacent ones of such slots forming twisted blanks therebetween. The individual blanks may then be subsequently machined to final shape such as an airfoil configuration.
