Conventional and nonconventional types of machining processes
Electronbeam machining (EBM) In any material, the EBM process is used to cut fine holes and slots. A beam of highvelocity electrons is focused on a workpiece in a vacuum chamber. When electrons collide with a workpiece, their kinetic energy is converted to heat, which vaporizes small portions of the material.

Electro Chemical Machining (ECM) Surface Characteristics
Basics of ECM Electro Chemical Machining (ECM) is an electrochemical reaction caused by applying a DC potential between two electrodes, a cathode (Tool) and an anode (Workpiece). In the simple cell (Fig. ) two electrodes are placed in a conductive salt solution such as sodium chloride. Because there is an electrical potential between the ...
