What is Electrical Discharge Machining (EDM) Process and ...

Apr 12, 2017· Electrical Discharge Machining (EDM) is a non traditional machining and electro thermal process in which material from the workpiece is removed by using electrical discharges (sparks). It was first observed in 1770 by Joseph Priestley. He was an English physicist. In EDM machine the material is removed by rapidly recurring (repeating) discharges of current in between the electrodes.

Centerless grinding - Wikipedia

Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; the workpiece is secured between two rotary grinding wheels, and the speed of their rotation relative to each other determines the rate at which material ...

Electric Discharge - an overview | ScienceDirect Topics

Electric discharge machining is a method of machining in which, as shown in Figure 1, when an electrode and a workpiece are brought closer to each other with pulse voltage being applied between them, dielectric breakdown occurring at a certain distance between them triggers discharge, whose high temperature and pressure in turn cause part of the workpiece to be melted and blown.

Electron - Wikipedia

The electron is a subatomic particle, symbol e − or β −, whose electric charge is negative one elementary charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton.
