Abstract
A cutting tool assembly using a machined tool operating in a plunge mode of electrical discharge machining to make microreplicated features in a work piece having a complex surface. The microreplicated features can be non-adjacent and can have any geometric configuration and micron-scaled dimensions, as determined by the microstructured features in the tool. The machined work piece can be used as a master tool in order to make microreplicated articles such as optical films, friction control films, plasma display panel molds, or micro-fasteners.
