Solution

There are two major types of EDM, Wire EDM and Sinker EDM (sometimes called Ram or Conventional EDM). The main difference between the two is the type of electrode used. Wire EDM, as its name suggests, uses wire as the electrode. Certain parts can only be produced using sinker EDM, which, unlike wire EDM, does not cut all the way through the part. As its name implies, Sinker EDM literally \"sinks\" a required shape into the workpiece.
