Shaping Processes-Non Traditional Machining
Machining is the process of removing material from a workpiece
The term "non-traditional machining process" refers to a component's manufacturing process that uses contemporary technology in place of conventional techniques. Other names for the non-traditional machining technique are contemporary machining and non-conventional machining.
Machining categories
Cutting
uses cutting instruments with either single-point or multipoint geometries that are well specified.
Abrasive
such as grinding.
Nontraditional
making use of optical, chemical, and electrical energy sources.
Nontraditional Machining
Ultrasonic Machining (USM)
the presence of vibrations above 20 kHz, which is higher than the human ear's top hearing limit.
• Water-Jet Machining & Abrasive-Jet Machining
is a type of machining where a mixture of grained particles (10–40 microns) and air or another gas is used to cut the material.
• Chemical Machining
The earliest unconventional machining method is essentially an etching procedure.
• Electrochemical Machining (ECM)
An electrochemical reaction to the tool's form dissolves the workpiece.
• Electrical-Discharge Machining (EDM)
typically employed for hard material machining. The right energy variation and spark time regulate the material discharge.
• High-Energy-Beam Machining
– Laser-beam machining (LBM)
When a laser beam is directed correctly onto a workpiece, it raises the temperature where it makes contact. The temperature attained exceeds the melting point, causing the metal to evaporate at the surface.
– Electron-beam machining (EBM)
is a type of machining where the metal is removed from the workpiece using an electron beam.
Plastic Arc Machining (PAM)
is a low-cost machining technique that cuts the workpiece with plasma.
