Advantages of ultrasonic machining : The cost of metal removal is low. As there is no heat generation in this process, there is no change in the physical properties of the job during machining. There are no residual stresses in the machined workpiece.Disadvantages of Ultrasonic Machining : The major limitation of the ultrasonic machining process is its comparatively low metal cutting rates.
Electrical Discharge Machining (EDM) Electrical discharge machining (EDM) is one of the most widely used non-traditional machining processes. The main attraction of EDM over traditional machining processes such as metal cutting using different tools and grinding is that this technique utilises thermoelectric process to erode undesired materials from the work piece by a series of discrete ...

The Non-Traditional Machining methods include, Ultrasonic Machining, Laser Beam Machining, Water Jet Machining, Abrasive Water Jet Machining, Electron Beam Machining, etc. which were presented in this article in a detailed way.
Electrochemical grinding (ECG) joins electrochemical machining with regular grinding. The gear utilized is like an ordinary processor. The wheel is a pivoting cathode installed with grating particles. The wheel is metal bonded with diamond or aluminum-oxide abrasives and turns at a surface speed from 1,200 to 2,000 m/min (4,000 to 7,000 ft/min).

Electrochemical cutting is a balance between unsupported grinding action and electrochemical erosion. It is a trade-off being between the speed of the grinding wheel and the burr removal of the far slower chemical action. Some Advantages of ECC. Electrochemical cutting can produce smooth edges without the burrs caused by mechanical grinding.

Electrochemical Machining is a non-traditional machining process in which metal removed by electrochemical dissolution. Now days this process widely used in many industries due to its advantageous ...
Electrochemical machining is the reverse of electroplating. An electrolyte works as a current carrier, and the high rate of electrolyte flow in the tool-workpiece gap washes metal ions from the workpiece (anode) before they have a chance to plate onto the tool (cathode). Modification of this process are used for turning, facing, slotting ...
Cubic boron nitride is commonly known as BorazonTM CBN, and is a man-made synthetic abrasive. CBN is made from cubic boron nitride grains bonded by ceramic material. It is as hard as diamond on the Mohs scale, making it well suited for ferrous materials in lapping operations, as it will not carbonize when interacting with iron (Fe), as diamond ...
