Abstract

A method of machining at least one tool in a set of press tools includes electrochemically machining the tool or tools using a preformed coactive or inter-active tool of the set as a machining electrode. Specified sets of tools are (a) a flanging punch and die set, (b) a cavity sinking punch and die set, (c) a blanking punch, die, stripper plate and blank ejector set, and (d) a punch and steel rule die set. The tool forming the machining electrode may itself have been formed by electrochemical machining. It may have an insulating coating over any portion which is not required to effect machining. Specification 985,334 is referred to.
