Non Conventional Machining Process Ppt 2021 [DIRECT]

The fundamental differences between conventional and non-conventional machining are crucial to understanding their respective roles.

These methods use localized heat energy to melt, vaporize, or erode material from the workpiece. Laser Beam Machining (LBM) Electron Beam Machining (EBM) Plasma Arc Machining (PAM) Chemical and Electrochemical Machining

Lower thermal distortion and improved surface integrity. Non Conventional Machining Process Ppt

These processes are essential for machining extremely hard, brittle, or difficult-to-cut materials (such as titanium, ceramics, or hardened steels) into intricate, complicated shapes, often used in aerospace, medical, and electronics industries. 1. Introduction to NTM Process (Overview)

: Unlike conventional methods (turning, milling), NCMP does not rely on the relative hardness of the tool over the workpiece. 2. Classification of Processes These processes are essential for machining extremely hard,

Scaled-down versions of ECM and EDM used to fabricate micro-electromechanical systems (MEMS) and medical implants. Conclusion

Manufacturing surgical instruments, orthopedic implants, and stents using LBM. Automotive: Fuel injection nozzles shaped with micro-EDM. The fluid acts as a coolant

A high-velocity stream of gas (air or nitrogen) loaded with fine abrasive particles focuses through a miniature nozzle onto the workpiece to cause micro-abrasive wear.

Kerosene, deionized water. The fluid acts as a coolant, spark insulator, and flushing medium for debris.

Traditional machining methods like turning, milling, and drilling rely on physical contact and a tool that is harder than the workpiece. However, as modern engineering demands harder, more complex, and more delicate components, have become essential.
