Electrical Discharge Machining (EDM) Process Explained


Wire EDM, Sinker EDM and Small Hole EDM are the three fundamental pillars of EDM Machining. Each one is a unique process, utilizing a different type of machine, each with a different way in which the electrode and workpiece are engaged to produce a final result.

The Wire EDM method is the most widely used in volume and is commonly utilized to manufacture and produce numerous components for aerospace, medical and manufacturing industries. This includes but is not limited to; tool & die components, punches, tooling, splines, extrusion dies, air foils, turbine blade components, internal and external gears, keyways, slots, medical devices, instruments, and prototypes that are intricate in design with incredible tolerances held.

Electrical conductivity is the unifying requirement with all of these components. The material of the workpiece must be electrically conductive for the electrical discharge machining process to work. If not conductive, complications will arise to varying degrees from poor cycle times to incapability of production. Machining with optimal conditions will greatly increase the productivity and efficiency of the overall process, thus keeping part costs to a minimum, and repeatable conditions at a consistent rate.

A superior level of accuracy, tightened tolerances and an increased surface finish can be achieved through EDM that conventional machining methods cannot normally ascertain. Intricate details and a small kerf are also unique to EDM as small diameter wire can be used, that which would not be possible in traditional machining methods. This is due to the fact that the Wire EDM cutting process exerts no cutting force or tooling pressure onto the part. There is no residual stress caused and little changes in the mechanical and thermal properties of the target material are imposed.
