Non-conventional (or Unconventional) machining refers to a group of processes that remove excess material by various techniques involving mechanical, thermal, electrical, or chemical energy—or combinations of these.

In the world of modern manufacturing, the demand for high-strength, temperature-resistant alloys (Inconel, Titanium, Hastelloy) and miniaturized components has rendered traditional turning, milling, and drilling obsolete for many applications. This is where step in.
Capable of machining materials like titanium, ceramics, and superalloys (Inconel).
Die sinking, mold making, drilling small holes.
To ground the technical discussion in reality, your PPT should showcase where these processes are making a difference and what the future holds. A tool vibrates at ultrasonic frequencies ( #Manufacturing
As electronics get smaller, Micro-EDM and Micro-ECM are becoming essential for medical implants and smartphone components.
Modern EDM machines use AI algorithms to monitor spark stability, instantly adjusting voltage pulses to prevent wire breakages.
This structured outline provides complete slide text for a comprehensive presentation on Non-Conventional Machining (NCM) processes, updated with 2026 trends.

Conclude your presentation by reinforcing that non-conventional machining is not an alternative to, but an indispensable extension of, the manufacturing engineer's toolkit. As we push the boundaries of material science and component complexity, these processes become the only viable pathway to production. The continuous stream of research and development—from bipolar EDM pulses to active gas-film insulation—shows a vibrant field that is enabling the next generation of technology in aerospace, medicine, automotive, and beyond. An updated PPT on this subject is not just a lecture on machining; it is a narrative of human ingenuity overcoming physical limitations to shape the future. Capable of machining materials like titanium, ceramics, and
Whether you are a manufacturing student prepping for a presentation or an engineer looking to refresh your knowledge, non-conventional machining (NCM) is a fascinating field. Standard tools like lathes and mills are great, but they struggle with super-hard materials or complex, microscopic shapes.
Micro-electro-mechanical systems (MEMS) and medical implants require completely stress-free, burr-free surfaces without heat-affected zones (HAZ).
These processes are classified based on the energy source used for material removal [1]. A. Mechanical Energy Processes
Reverse electroplating where material is dissolved anodically.
