Non Conventional Machining Process Ppt -

Non-conventional machining (NCM) processes, often called non-traditional machining, represent a group of advanced manufacturing techniques that remove material using various energy forms—electrical, thermal, chemical, or mechanical—without direct physical contact between a sharp cutting tool and the workpiece. These processes were developed to overcome the limitations of traditional machining, such as the inability to machine extremely hard or brittle materials and the difficulty of creating complex, intricate geometries. Classification of Non-Conventional Machining

1. Mechanical: Ultrasonic Machining (USM), Abrasive Jet Machining (AJM), Water Jet Machining (WJM).
2. Electro-Chemical: Electrochemical Machining (ECM), Electrochemical Grinding (ECG).
3. Chemical: Chemical Milling (CHM).
4. Thermo-Electrical: Electric Discharge Machining (EDM), Laser Beam Machining (LBM), Plasma Arc Machining (PAM), Electron Beam Machining (EBM).

Material Hardness: Can machine carbides, ceramics, and heat-resistant alloys. Complexity: Ideal for micro-holes and intricate 3D shapes. Non Conventional Machining Process Ppt

Slide 7: Electrochemical Machining (ECM)

• Principle: Reverse electroplating – anodic dissolution using electrolyte.
• Advantages: No tool wear, no heat, mirror finish.
• Applications: Turbine blades, fuel injector nozzles.
• Visual: Schematic showing tool (cathode) and workpiece (anode).

Slide 10 — Case Study (concise)

• Example: EDM for mold cavities in hardened tool steel — setup, electrode choice, typical parameters, results (surface finish ~Ra 0.8–3.2 µm, accuracy ±0.02 mm).

Slide 2: Beyond the BladeElias realized that to conquer this material, he had to stop thinking about "cutting" and start thinking about "energy." He moved away from Conventional Machining—where tools physically grind against workpieces—and entered the world of Non-Conventional Machining (NCM). Here, there are no sharp metal edges; instead, we use mechanical, thermal, electrical, and chemical energy. there are no sharp metal edges
