Machining Process
Machining is defined by the process of removing excess material from the work piece to obtain the desired shape and size of a final product.
Classification of Machining Process
Depending upon the type of machine tools that are used for machining, machining processes can be classified as follows:
1. Traditional or, Conventional Machining
Example- Turning, Milling, Drilling, Broaching etc.
2. Non-Traditional or, Unconventional Machining
Example- WJM, AJM, USM, CHM, ECM, EDM, EBM, LBM, PAM etc.
Traditional Machining ProcessIn traditional or conventional machining processes material removal is done by relative motion between the tool and work piece in the form of chips by shearing action.
Example- Turning, Milling, Drilling, Shaping, Planning etc.
Non-Traditional or Unconventional Machining Process
In non-traditional machining process the metal removal is done by various processes like
• by chemical corrosion in CHM
• by electrochemical dissolution in ECM
• by electric spark in EDM
• by kinetic energy of high-speed electrons in EBM
• by shear erosion in USM
• by powerful laser radiation in LBM
Names of different Non-Traditional Machining Process
• AJM = Abrasive Jet Machining
• WJM = Water Jet Machining
• USM = Ultrasonic Machining
• CHM = Chemical Machining
• ECM = Electro Chemical Machining
• EDM = Electro Discharge Machining
• EBM = Electron Beam Machining
• LBM = Laser Beam Machining
• PAM = Plasma Arc Machining
Disadvantages of Traditional Machining Process
Or, ‘Why non-traditional machining processes are required?’
In traditional machining processes following problems can’t be solved:
1. Machining Hard or Brittle Materials
2. Complex Shapes and Geometries can be machined
3. Reduced Mechanical Stresses generated due to non contact of tool and workpiece
4. Minimal Tool Wear due to no contact between the tool and the workpiece
