These utilize chemical reactions or electrochemical dissolution to remove material.
NCM processes use thermal, chemical, electrical, or mechanical energy to shape materials without direct tool-to-workpiece contact. This article provides an up-to-date, comprehensive breakdown of advanced manufacturing technologies, perfectly structured for academic and professional presentations. Why Non-Conventional Machining? Limitations of Conventional Machining
involves the selective removal of material through chemical reactions. By masking specific areas, manufacturers can achieve precise etching on thin parts and panels, making it suitable for applications in aerospace and electronics.
These processes melt, vaporize, or fuse material using extreme localized heat. non conventional machining process ppt updated
Spark erosion. The tool and workpiece never touch; a spark gap of is maintained.
Pure water jet (WJM) uses ultra-high-pressure water (
Piezoelectric transducer, concentrator/horn, tool, and abrasive delivery system. Why Non-Conventional Machining
Non-conventional machining processes have fundamentally transformed modern manufacturing. They enable the precision machining of advanced materials—high‑strength alloys, ceramics, composites, and superalloys—that would be impossible or uneconomical to process using conventional methods. Their ability to produce complex geometries, micro‑scale features, and burr‑free surfaces with minimal thermal damage makes them indispensable for high‑value industries including aerospace, medical devices, automotive, electronics, and defense.
The workpiece must be electrically conductive. Ultrasonic Machining (USM)
These processes use kinetic energy or mechanical erosion to micro-chip materials away. These processes melt, vaporize, or fuse material using
Non-Conventional Machining (NCM) processes—also known as Advanced Machining Processes (AMP)—remove material without direct, forceful tool-workpiece contact. This article provides a comprehensive, slide-by-slide structure and detailed content perfectly optimized for creating an updated presentation (PPT) on this critical manufacturing topic.
