What is EDM wire cut?

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.

What causes metal to move when it is cut with wire EDM?

Even though metal has been stress relieved, it may move after the part has been cut with wire EDM because the stresses within the metal were not totally removed in stress relieving.

What are the units required for wire cut EDM process?

Explanation: In the wire-cut EDM process, water is commonly used as the dielectric fluid. Filters and de-ionizing units are used for controlling the resistivity and other electrical properties.

What is EDM method?

Electrical discharge machining (EDM) is a non-traditional machining process based on removing material from a part by means of a series of repeated electrical discharges between tools, called electrodes, and the part being machined in the presence of a dielectric fluid. From: Machining and machine-tools, 2013.

What is the principle of EDM?

Principles of EDM Electrical Discharge Machining (EDM) is a controlled metal-removal process that is used to remove metal by means of electric spark erosion. In this process an electric spark is used as the cutting tool to cut (erode) the workpiece to produce the finished part to the desired shape.

What is the Wedm?

Wire electrical discharge machining (WEDM) is a non-conventional machining process used for hard to cut conductive material. Wire EDM finds many applications; for instance, in the manufacturing of various press tools, dies and even electrodes used in other areas of EDM.

How do you calculate wire cut time?

To calculate the time, take the periphery of the part, one time around, divided by the A.L.F. (Average Linear Feed Rate) value shown for the last pass of the cut you will be taking. The resulting value will give you the machining time.

What are the types of EDM instruments?

The electronic distance measuring equipment is differentiated into three types as, microwave instrument, infra red equipment and light wave equipment.
