What is meant by the term 'EDM cycle'?

The term 'EDM cycle' refers specifically to the sequence of operations that take place during the process of electrical discharge machining (EDM). EDM is a non-traditional machining process that uses electrical discharges (sparks) to remove material from a workpiece.

In an EDM cycle, several steps are typically involved, including the setup of the workpiece and electrode, the establishment of the dielectric fluid to facilitate the discharge, and the actual machining process where electrical sparks occur. These sparks erode the material from the workpiece in a controlled manner. Understanding the EDM cycle is crucial for optimizing the machining process, as it encompasses key factors like the control of voltage, the timing of the discharge, and the management of the dielectric fluid, all of which affect machining efficiency and accuracy.

Other concepts like cutting metal with lasers or measuring tool efficiency do not pertain to the specific sequence of operations involved in electrical discharge machining, nor does the cooling process after machining relate to the EDM cycle. Therefore, recognizing the sequence of operations is essential for effectively employing and refining EDM processes.
