Use this table as a "Summary Slide" to give your audience a clear takeaway. Traditional Machining Non-Conventional Machining Tool Material Must be harder than workpiece Material hardness is irrelevant Tool Contact Physical contact required No physical contact Material Removal Plastic deformation (chips) Erosion, melting, or dissolution Surface Finish Moderate to Good Excellent / High Precision High (large chips) Low (micro-particles/sludge) 💡 Tips for a Winning PPT Presentation Use High-Quality Diagrams:
"Generate a 20-slide outline for an updated PowerPoint on Non-Conventional Machining Processes. Include Hybrid processes (Laser-ECM), Green manufacturing (Dry EDM), Micro-machining (FIB), and AI integration for surface roughness prediction. Target audience: 4th-year Mechanical Engineering students and Industry professionals. Provide slide titles and 3 bullet points per slide."

Types of Machining Operations: Classifications and Differences
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 Green manufacturing (Dry EDM)
Based on Faraday’s Laws of Electrolysis. The workpiece acts as the anode (+), and the pre-shaped tool acts as the cathode (-). A rapid stream of electrolyte (like NaCl or NaNO3 dissolved in water) pumped through the gap facilitates atomic-level dissolution. Critical Presentation Points:
