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
The Limitations of Conventional Machining (The "Why")
The reverse of electroplating. The workpiece acts as an anode, and the tool acts as a cathode in an electrolyte solution. Current flows through the electrolyte, dissolving material from the workpiece with zero tool wear. 3. Thermo-Electrical Energy Processes non conventional machining process ppt updated
