​

Answer 1

Answer:

Electrochemical Machining (ECM) – Working Principle, Equipment, Advantages and Disadvantages with Application. 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.

Answer 2

Answer:

1.Electrochemical machining uses both an electrolyte solution and an electrical current to alter the workpiece. ... These are both placed in an electrolyte solution and an electrical current is passed through the solution between them. The workpiece and tool are placed very close to each other but are not touching.

2.Ultrasonic Machining (USM) also called as ultrasonic vibration machining is a machining process in which material is removed from the surface of a part by low amplitude and high frequency vibration of a tool against surface of material in the presence of abrasive particles.
