Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.
However, in some applications, the workpiece rotates during the erosion process. Cylindrical wire electrical discharge turning (CWEDT) is an example of such a process. According to Haddad and Tehrani (2008) and Mohammadi et al. (2008), in CWEDT a rotary axis is added to the machine to manufacture axisymmetric parts.
