In wire electrical discharge machining wedm also known as wire cut edm and wire cutting a thin single strand metal wire usually brass is fed through the workpiece submerged in a tank of dielectric fluid typically deionized water. Takes shape opposite to that of cutting tool electrode cutting tool made from electrically conductive material dielectric fluid surrounds both tool and work servo mechanism gives gap 005 to 001 in. 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 thin single strand metal wire usually brass is fed through the workpiece submerged in a tank of dielectric fluid typically deionized water.

With wire edm you can basically cut out any design. A separate edm head specifically for small hole drilling is mounted on a wire cut machine and allows large hardened plates to have finished parts eroded from them. General electric uses 36 wire edm machines to cut steam turbine bucket roots. After the parts are edmed a non contact video inspection system interfaced with a computer system automatically examines the work.

Used to cut plates as thick as 300 mm and to make punches tools and dies from hard metals that are difficult to. Introduction history discussion references 3. Wire cut edm wire cutting edm cutting wire burning wire erosion and cheese cutter edm. Wire edm is also known as.

Wire cut edm is typically used to cut plates as thick as 300mm and to make punches tools and dies from hard metals that are difficult to machine with other. Deionized water is used as the dielectric. Wire cut edm 1. Electric discharge machining edm sometimes colloquially also referred to as spark machining spark eroding burning die sinking or wire erosion is a manufacturing process whereby a desired shape is obtained using electrical discharges sparks.

The robot moves on a track between the two rows of wire edm machines. Presentation on wire edm ppt 2. Electrical discharge machining wire cutting edm wc is a thermal mass reducing process that uses a continuously moving wire to remove material. Small hole drilling on wire cut edm machines small hole drilling edm is used to make a through hole in a workpiece in through which to thread the wire for the wire cut edm operation.

A thin wire of brass tungsten or copper is used as an electrode. Simple cuts are done by varying the x y coordinates of the cutter with more complex cuts achieved by adding axes of motion to the wire guides. Principle of edm controlled metal removal technique where electric spark used to cut erode workpiece. 46 edm types wire edm wedm also known as wire cut edm and wire cutting.
