Wire Cut Edm Machine Working Principle

Wire cut edm wire cutting edm cutting wire burning wire erosion and cheese cutter edm.

Wire cut edm machine working principle.

It was first observed in 1770 by joseph priestley. Wire edm is also known as. 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. A water jet or air jet guides the wire through the work piece.

Numerous tiny holes appears due to erosion of impulse discharging and therefore get the needed shape of workpiece as show in figure 1 1. In edm machine the material is removed by rapidly recurring repeating discharges of current in between the electrodes. 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. Modern wire edm machines provide automatic threading.

The machine automatically makes the necessary mechanical and electrical connections. 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. 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. 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.
