Real-time monitoring using machine learning to dynamically adjust pulse frequencies, dielectric flow rates, and feed speeds to prevent wire breakage and micro-cracking.
Machine learning algorithms now monitor spark stability in EDM and pulse width in LBM in real-time to adjust parameters automatically, eliminating human error.
Reflective materials (like copper and aluminum) require specific fiber laser wavelengths for efficient absorption. 4. Deep Dive: Chemical and Electrochemical Processes Electrochemical Machining (ECM)
Highlight that the tool itself does not cut the material; the abrasive grains in the slurry perform the erosion. Abrasive Jet & Water Jet Machining (AJM / WJM) non conventional machining process ppt updated
Hardened steels, carbide tools, and complex blind cavities.
If conductive, choose EDM, WEDM, or ECM. If non-conductive, choose USM, LBM, or AJM.
These processes use a high-pressure (up to 600 MPa), high-velocity (up to 900 m/s) jet of water to cut materials. For harder materials, abrasives are added to the jet (AWJM), enabling it to cut through steel, titanium, and composites without generating a heat-affected zone (HAZ)—a critical advantage for heat-sensitive materials. If conductive, choose EDM, WEDM, or ECM
Electrochemical Machining (ECM) and Ultrasonic Machining (USM). Highest Precision: Laser Beam Machining (LBM) and Wire-EDM. 6. Future Trends in Advanced Machining
Non-conventional machining processes do not replace conventional methods; they complement them when traditional methods reach their physical limits.
By understanding the principles and applications of non-conventional machining processes, manufacturers can expand their capabilities, improve productivity, and produce high-quality parts with complex shapes and precision finishes. When building your presentation slides

A localized spark generates temperatures between 8,000°C and 12,000°C. This melts and vaporizes a microscopic volume of material. The dielectric fluid then flushes the vaporized metal particles away. Variants:
That’s where come in.
