Uses a high-velocity jet of ionized gas (plasma) to melt and blow away conductive metals. 3. Chemical and Electrochemical Processes
A tool vibrates at high frequencies (20 kHz to 40 kHz) within an abrasive slurry (such as boron carbide or silicon carbide). The microscopic grains are hammered against the workpiece, fracturing and eroding it. Non Conventional Machining Process Ppt
Non-conventional machining processes do not use traditional, sharp cutting tools to carve out designs. Instead, they leverage specialized energy sources to achieve precision, enabling the machining of extremely hard, brittle, or complex materials that are impractical for conventional methods. Uses a high-velocity jet of ionized gas (plasma)
The workpiece and a shaped tool (electrode) are submerged in a dielectric fluid (like kerosene or deionized water). A pulsating DC power supply creates a high voltage difference between them. When the gap becomes small enough, the dielectric breaks down, creating a spark. The spark generates temperatures up to 10,000°C, melting and vaporizing a micro-speck of metal. The microscopic grains are hammered against the workpiece,
