Non Conventional Machining Process Ppt Updated

Creating an effective PPT begins with establishing this context. Your opening slides should highlight the core "why": the need to machine complex shapes, achieve high precision, and work with challenging materials that push conventional tools to their limits. The key differentiation points include:

Uses spark discharges in a dielectric fluid. It's the "gold standard" for creating complex molds and dies.

Extremely high precision; ideal for micro-drilling and micro-cutting. No tool wear since light is the tool.

No thermal heat-affected zone (HAZ), making it perfect for heat-sensitive materials.

: A highly concentrated, coherent monochromatic light beam focuses onto the workpiece. The intense optical energy converts to thermal energy, rapidly melting and vaporizing the targeted zone. Materials : Metals, plastics, ceramics, and rubber.

Die and mold making, aerospace components, and prototype development. Ultrasonic Machining (USM)

Non-conventional machining processes (NCMP) remove material using alternative energy sources like thermal, chemical, or electrical energy instead of direct physical contact from a harder tool . These are critical for machining extremely hard, brittle, or complex materials that standard methods cannot handle.

The workpiece and a shaped tool electrode are submerged in a dielectric fluid (like kerosene or deionized water). A high-frequency pulsed DC voltage creates spark discharges across a microscopic gap. This intense spark vaporizes and melts the material. Critical Presentation Points: Creating an effective PPT begins with establishing this

They can create intricate shapes that a physical tool cannot reach.

Traditional machining methods like turning, milling, and drilling rely on physical contact between a harder cutting tool and a softer workpiece. These conventional processes fail when industries require the fabrication of ultra-hard, brittle, or extremely complex materials.

Cuts soft materials using a ultra-high-pressure jet of pure water.

Setting up lasers, vacuum chambers (EBM), or advanced power supplies requires significant investment.

Based on Faraday's Laws of Electrolysis. The workpiece acts as the anode (+), and the tool acts as the cathode (-). A high-velocity electrolyte solution (like NaCl or NaNO3) passes through the gap. When a low-voltage, high-current DC is applied, material dissolves atom-by-atom from the workpiece.
