Non Conventional Machining Process Ppt High Quality (Recent)

Non-conventional machining (NCM) processes, such as ultrasonic, electric discharge, and laser beam machining, utilize thermal, chemical, or electrical energy rather than direct tool contact to shape hard or brittle materials . These methods offer high precision and complex geometry capabilities, overcoming the limitations of traditional machining despite often having lower material removal rates . For a detailed academic overview of these processes, see the resources from IIT Kanpur and IIT Bombay. Introduction to Non-Traditional Machining - IIT Kanpur

Non-Conventional Machining (NCM) processes, also known as advanced or non-traditional machining, are specialized manufacturing techniques that remove material using various forms of energy (mechanical, thermal, electrical, or chemical) instead of direct physical contact with a sharp cutting tool . These processes are essential for machining extremely hard or brittle materials and creating complex geometries that traditional methods like milling or turning cannot handle . Classification of NCM Processes

NCM processes are primarily classified by the type of energy used for material removal :

Mechanical Energy Processes: Use high-velocity particles or fluids to erode material.

Ultrasonic Machining (USM): Employs a vibrating tool and abrasive slurry .

Abrasive Jet Machining (AJM): Uses a high-velocity stream of abrasive particles . Non Conventional Machining Process Ppt

Water Jet Machining (WJM): Uses high-pressure water streams to cut .

Thermal/Electro-Thermal Energy Processes: Use heat to melt or vaporize material.

Electrical Discharge Machining (EDM): Removes metal via repetitive spark discharges in a dielectric fluid .

Laser Beam Machining (LBM): Uses a focused, high-intensity laser beam .

Electron Beam Machining (EBM): Uses a focused beam of high-velocity electrons . Slide 4: Abrasive Water Jet Machining (AWJM)

Electrochemical/Chemical Processes: Use chemical reactions or electrolysis.

Electrochemical Machining (ECM): Removes material atom-by-atom via electrolysis .

Chemical Machining (CHM): Uses etchants to selectively dissolve material . Comparison: Conventional vs. Non-Conventional Non-Conventional Machining Overview | PDF - Scribd

Slide 4: Abrasive Water Jet Machining (AWJM)

• Working Principle: High-pressure water + abrasive particles cut material.
• Advantages: No heat, no HAZ, cuts any material.
• Applications: Aerospace composites, stone, glass, titanium.
• Visual: Diagram of mixing tube and jet cutting plate.

Slide 1: Mechanical Energy Based Processes

• Abrasive Jet Machining (AJM): High-pressure gas mixed with abrasives cuts brittle materials.
• Water Jet Machining (WJM): Pure water cuts soft materials (foam, rubber).
• Abrasive Water Jet Machining (AWJM): Water + garnet cuts steel, titanium, and stone (No heat-affected zone).
• Ultrasonic Machining (USM): Low-frequency vibrations (20 kHz) with abrasive slurry create cavities in glass or ceramics.

This report outlines the essential structure and content for a presentation on Non-Conventional Machining Processes (NCMP), also known as Unconventional or Modern Machining. These processes are critical for manufacturing complex shapes in advanced materials that are too hard or brittle for traditional tools.  1. Introduction to Non-Conventional Machining  Water Jet Machining (WJM)

Definition: Processes that remove material using mechanical, thermal, electrical, or chemical energy without direct physical contact from a sharp cutting tool.

Need for NCMP: Developed to handle "difficult-to-machine" materials like carbides, hastelloy, and ceramics, and to achieve high-precision intricate shapes.

Comparison: Unlike conventional methods (turning, milling), NCMP does not rely on the relative hardness of the tool over the workpiece.  2. Classification of Processes
