Summary. Thin, stress-relieved, tool and die steel workpieces have been machined with s ingle-pass peripheral electrochemical grinding using a diamond grit wheel, then subjected to a residual stress analysis. Residual stress distributions are presented and these are representative of three fundamental removal modes associated with finish machining.

In 1956 electrochemical machining became commercial and the use of electrochemical energy to remove metal became common. The exact history of the development of electrochemical deburring is known, yet we can say that with growing demands of accurate products there was a need to discard burrs after machining.

Summary. Weld cleaning is a key post-welding process used to prevent corrosion on metal surfaces. Three weld cleaning methods are distinguished: Mechanical (grinding with abrasives) Chemical (pickling paste treatment) Electrochemical (Cleaning with electrolytic fluids) The mechanical process is fairly ineffective and time-consuming.

An electrochemical machining procedure ( ECM ) is an of import group of untraditional procedures use electrical energy to take stuff. This group is identified by the term electrochemical procedures, because electrical energy is used in combination with chemical reactions to carry through stuff remotion.

Electrochemical machining (ECM) is a machining process in which electrochemical process is used to remove materials from the workpiece. In the process, workpiece is taken as anode and tool is taken as cathode. The two electrodes workpiece and tool is immersed in an electrolyte (such as NaCl).
