Wire Cut Edm Machine Working Principle

Cnc wire cut edm machine puts impulse voltage between electrode wire and workpiece through impulse source controlled by servo system to get a certain gap and realize impulse discharging in the working liquid between electrode wire and workpiece.

Wire cut edm machine working principle. Modern wire edm machines provide automatic threading. Wire electrical discharge machining wedm uses a metallic wire to cut or shape a workpiece often a conductive material with a thin electrode wire that follows a precisely programmed path. A water jet or air jet guides the wire through the work piece. If the wire breaks while cutting a part the machine senses the break re threads the wire and resumes the cut where the wire broke.

Wire cut edm wire cutting edm cutting wire burning wire erosion and cheese cutter edm. He was an english physicist. Electrical discharge machining edm is a non traditional machining and electro thermal process in which material from the workpiece is removed by using electrical discharges sparks. Numerous tiny holes appears due to erosion of impulse discharging and therefore get the needed shape of workpiece as show in figure 1 1.

Wire edm is also known as. The machine automatically makes the necessary mechanical and electrical connections. Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes separated by a dielectric liquid and subject. In edm machine the material is removed by rapidly recurring repeating discharges of current in between the electrodes.
