Conventional EDM equipment first appeared in the early 1950s, and performed simple machining utilizing the phenomenon of electrical spark but utilizes five heads mounted above discharge.
Wirecut EDM machines a single table. The ability to stack came on the market in the early workpieces under each head to depths 1970s. The first five-head wirecut EDM arrived in the United States in December, 1980.
Until then, wirecut EDM had generally been used only for tool and die manufacture, prototype parts or intricate machining jobs that could be accomplished in no other way. Typical tolerances of +/- 0.0002″ have made the process highly attractive for precision machining. The reduction in machining steps has also reduced production times and costs for many operations.
The programmer provides dimensional data to a computer via a keyboard. Then the software within the computer will automatically generate either a punched paper tape or cassette, which will drive the wire EDM machine.
The abbreviation of wire cut EDM machine tool means an electric discharge machining machine for wire cutting. It can also be called spark machining and spark eroding in the industrial field. It uses electrical discharge to machine the work piece into the desired shape. Some countries interpret this process as sparking machining. Electric discharge machining is to remove the material of the work piece from the work piece through a series of rapidly recurring electric current.
