Ppt — Non Conventional Machining Process

Uses ionized gas (plasma) at extremely high temperatures. 3. Comparison: Conventional vs. Non-Conventional

No direct contact between the tool and the workpiece (in most cases).

Non-Conventional Machining Processes (NCMP): An In-Depth Overview Non Conventional Machining Process Ppt

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.

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? Uses ionized gas (plasma) at extremely high temperatures

Essential for micro-machining components used in medical devices and semiconductors.

Uses spark erosion between an electrode and the workpiece. Non-Conventional No direct contact between the tool and

The tool material doesn't necessarily need to be harder than the workpiece. High accuracy and the ability to machine complex 3D shapes.
