Abstract
Disclosed is an improved fixture assembly for use on an electrode wire EDM apparatus which is adapted to cut a conductive workpiece. Referring to FIG. 2, the improved fixture which can secure a plurality of workpieces 52 comprises master bar 40, which is secured to work supports 30 transversely therebetween, base plate 42 which is removably attached to the master bar at a predetermined location thereof and which has a plurality of equally-spaced support locations upon which each said workpiece rests, locator plate 44 which is removably attached to the base plate at a predetermined location thereof and which has a plurality of equally-spaced recesses of predetermined shape along an edge thereof for a side of each workpiece to be held thereagainst, and a plurality of pre-configured clamps 48 removably attached to the upper side of said locator plate which are tightenable to exert force against the top surface of each workpiece for securing the workpiece in a precise location for cutting. The edgewise profiles of all components of said fixture are adapted so that each workpiece is secured and all components are non-interfering with the predetermined cutting path. The preferred workpieces comprise polycrystalline abrasive compacts typified by polycrystalline diamond compacts preferably supported on a metal support.
