To structure your PPT effectively, classify these processes by the type of energy used: A. Mechanical Processes These use physical erosion to remove material.
Processes like USM or ECM operate with high precision and lower noise compared to heavy milling. 5. Conclusion for Your Presentation
Non-conventional (or unconventional) machining refers to a group of processes that remove excess material through various techniques involving mechanical, thermal, electrical, or chemical energy—or a combination of them.
Non-Conventional Machining Processes (NCMP): An In-Depth Overview
When presenting this topic, a comparison table is vital for clarity: Conventional Machining Non-Conventional Machining Direct physical contact No physical contact (usually) Material Removal Macroscopic chips Microscopic chips/atoms/melting Tool Life High wear and tear Minimal to zero tool wear Complexity Difficult for intricate shapes Excellent for complex geometries Cost Lower initial setup cost Higher initial investment 4. Why Use Non-Conventional Machining?
A high-pressure jet of water cuts through soft materials. B. Electrochemical Processes Material is removed via ion displacement.
Uses spark erosion between an electrode and the workpiece.
Essential for micro-machining components used in medical devices and semiconductors.
