Non Conventional Machining Process PPT

The is more than just a college assignment; it is the bridge between theoretical manufacturing science and industrial application. Whether you are explaining the ionization of a plasma torch or the dielectric breakdown in a spark gap, your slides must tell a story of problem, solution, and comparison .

  1. Hardness independent: Cut any hardness (e.g., 70 HRC).
  2. Complex 3D shapes: Square holes, curved internal cavities.
  3. Low stress: Particularly ECM and USM.
  4. High precision: Up to ±0.005 mm (EDM/ECM).

Slide 2 — Introduction

  • Principle: Spark erosion (5000–10000°C) between electrode (Cu/W) and workpiece submerged in dielectric fluid (kerosene/deionized water).
  • Key Parameters: Current, Pulse ON/OFF time.
  • Application: Die cavities, nozzles, holes in Inconel.
  • Conventional machining (lathe, milling, drilling) uses direct contact between tool and workpiece.
  • Limitations of conventional methods:

    Slide 3 — Classification (brief)
