ABSTRACT:
An improved method of electroerosively machining a two- or three-dimensional contour in a workpiece makes use of a worktable movable to displace the workpiece in an X-Y plane and a tool electrode having a plurality of divided machining electrode surfaces on its lateral periphery. The tool electrode is supported with a support member so as to be rotatable about a rotary axis orthogonal to the X-Y plane and so that each of the machining surfaces extends in parallel with the rotary axis. Motors for translational movement of the worktable and a motor for rotating the tool electrode are controlled by a command source, e.g. NC unit, to control the position of the workpiece and the angular orientation of the tool electrode so that the particular machining surfaces optimum to the particular configurations of successive portions of the contour that are to develop sequentially in the workpiece are presented in machining relationship with the workpiece.
