Abstract

A workpiece (1) may be formed in a desired form by placing the workpiece (1) in such a position that a surface (2) of the workpiece (1) is exposed and then subjecting the exposed surface (2) of the workpiece (1) to electrochemical machining. In particular a cathode (7) is advanced towards an anodic workpiece (1) in the presence of an electrolyte and a current is passed between the cathode (7) and the work piece (1) through the electrolyte so as to cause material to be removed electronically from the surface (2) of the workpiece (1). Vibrating movement can be applied to the cathode (7) and the current may also be varied. As a result the surface (2) of the workpiece (1) is shaped in a desired form (3).
