Non Conventional Machining Process Ppt Updated [extra Quality] May 2026

Non-conventional machining (NCM) processes—also known as non-traditional or advanced machining—remove material using thermal, chemical, electrical, or mechanical energy without direct physical contact between a tool and a workpiece. These processes are critical for machining extremely hard materials or complex geometries that traditional methods like milling or turning cannot handle. Comprehensive Presentation Resources

Uses strong etchants (chemicals) to remove material from specific areas. 3. Thermal/Electro-Thermal Processes These use intense heat to melt or vaporize the material. Electrical Discharge Machining (EDM): Uses "sparks" to erode the workpiece. Laser Beam Machining (LBM): A highly focused light beam melts the surface. Plasma Arc Machining (PAM): Uses ionized gas at extremely high temperatures. 📊 Comparison Table: Traditional vs. Non-Conventional non conventional machining process ppt updated

    Slide 7: Water Jet Machining (WJM)

    • Principle: A high-velocity jet of pure water (up to 4000 bar) cuts soft materials.
    • Abrasive Water Jet (AWJM): Water mixed with abrasives for cutting harder materials (steel, stone).
    • Applications: Cutting foils, plastics, paper, leather, food products, and metals (AWJM).
    • Advantages: No heat affected zone (HAZ), no dust, high cutting speed for soft materials.
    • Limitations: High initial cost, requires high-pressure sealing maintenance.
