NCM is visual. Include cross-section diagrams of an EDM tank or a Laser head. Add Video Clips:

Can produce highly complex, intricate shapes with high dimensional accuracy.

The updated presentation on Non-Conventional Machining Processes demonstrates a solid effort to modernize the content. The inclusion of recent advancements (e.g., Hybrid machining, EDM with AI integration, Water Jet Guiding Laser) is a strong plus. However, the slide density and lack of comparative data visuals slightly hinder the learning flow.

: Processes that remove material without direct physical contact between a sharp tool and the workpiece.

Modern engineering leans heavily on NCMPs due to strict design tolerances:

Easily cuts complex, three-dimensional shapes and deep, narrow holes. Classification of Non-Conventional Machining Processes

: Crafting turbine blade cooling holes using EDM and ECM, alongside profiling complex wing components via AWJM.

An advanced presentation should guide the audience on how to think through process selection. You can dedicate a slide that outlines a decision matrix based on key factors, including:

These processes erode material via high-velocity erosion or abrasion using abrasive grains or fluid impacts. Ultrasonic Machining (USM) Abrasive Jet Machining (AJM) Water Jet Machining (WJM) Abrasive Water Jet Machining (AWJM) B. Electrochemical Energy Processes

High cutting forces lead to the deformation of thin-walled components. Key Advantages of NCM

Certain methods are limited by material properties (e.g., EDM and ECM only work on electrically conductive materials). 6. PPT Slide Outline & Presentation Summary

: Necessary for modern materials (superalloys, ceramics, composites) that are too hard, brittle, or delicate for traditional milling/turning.

Non-conventional machining (NCM) processes, also known as modern or non-traditional machining, remove material using advanced energy sources like thermal, chemical, or electrical energy rather than direct physical contact with a sharp cutting tool. As of April 2026, the field is rapidly evolving with integrations of and hybrid additive-subtractive manufacturing . I. Comparison: Conventional vs. Non-Conventional
