Wire Cut Edm Machine Working Principle

Electrical discharge machining edm also known as spark machining spark eroding die sinking wire burning or wire erosion is a metal fabrication process whereby a desired shape is obtained by using electrical discharges sparks.

Wire cut edm machine working principle.

Wire cut edm wire cutting edm cutting wire burning wire erosion and cheese cutter edm. 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 edm is also known as. 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.

Numerous tiny holes appears due to erosion of impulse discharging and therefore get the needed shape of workpiece as show in figure 1 1. A water jet or air jet guides the wire through the work piece. 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. Modern wire edm machines provide automatic threading.

In edm machine the material is removed by rapidly recurring repeating discharges of current in between the electrodes. He was an english physicist. The machine automatically makes the necessary mechanical and electrical connections. Wire edm machining electrical discharge machining is an electro thermal production process where a thin single strand metal wire along with de ionised water used to conduct electricity allows the wire to cut through metal by the use of heat from electrical sparks while preventing rust.
