To structure your PPT effectively, classify these processes by the type of energy used: A. Mechanical Processes These use physical erosion to remove material.
| Parameter | Conventional | Non-Conventional | | :--- | :--- | :--- | | | Harder than workpiece (HSS, Carbide) | No physical contact or softer/conductive material (e.g., graphite) | | Mechanical Forces | High clamping forces required | Very low or zero forces | | Heat Generation | Frictional heat in shear zone | Controlled heat, or no heat (ECM, USM) | | Geometric Complexity | Limited by tool access | Virtually unlimited (holes at angles, micro-features) | | Material Hardness | Cutting becomes impossible above 45 HRC | No correlation with hardness |
Non-conventional machining processes (NCMP)—also known as advanced machining processes—have revolutionized modern manufacturing. As industries push toward miniaturization, high precision, and the use of ultra-hard materials, traditional cutting tools often fail. Traditional methods rely on a harder tool physical contacting and removing chips from a softer workpiece. In contrast, non-conventional processes utilize thermal, chemical, electrical, or mechanical energy to shape materials without direct tool-to-workpiece contact stresses.

The story shifts when scientists stopped trying to "cut" and started trying to "erode." They moved away from direct tool contact and looked toward the elemental: To structure your PPT effectively, classify these processes
Lower material removal rates (MRR) compared to traditional heavy milling. Significant initial capital investment and operating costs. High power consumption demands.
Non-conventional machining processes (NCMP) have transformed modern manufacturing. Traditional methods like turning, milling, and drilling rely on direct contact and mechanical force. In contrast, advanced manufacturing uses thermal, chemical, electrical, or high-velocity fluid energy to shape tough materials. What is your

Any questions?
Why are these processes necessary? Traditional machining methods like turning, milling, and drilling have limitations. They struggle with materials that are exceptionally hard, brittle, tough, or highly flexible. As industries demand more advanced materials and complex part geometries, the need for alternative methods becomes clear. Non-conventional processes are often the only viable solution for:
