Combining EDM with Ultrasonic vibrations (USM-EDM) significantly increases material removal rates and helps flush debris more effectively. non conventional machining process ppt updated
A high-speed gas stream carries abrasive particles to erode the surface [3].
When building your presentation slides, use this structured comparison table to summarize the key performance indicators of each major process: Energy Source Material Removal Mechanism Primary Materials Covered Surface Finish ( Racap R sub a Tool Wear Rate Mechanical Brittle fracture / erosion Glass, Ceramics, Quartz 0.2 – 0.8 AWJM Mechanical Erosion by abrasive impact Metals, Composites, Stone 1.6 – 6.3 Low (Nozzle wear) ECM Electrochemical Ion displacement / Dissolution All conductive metals 0.1 – 0.4 EDM Melting and Vaporization All conductive metals 0.2 – 1.2 LBM Vaporization Metals, Plastics, Ceramics 0.4 – 2.0 CHM Controlled chemical etching Aluminum, Titanium, Steel 1.0 – 4.0 6. PPT Update: Modern 2026 Trends in NCM : Manufacturing complex dental implants and surgical tools
This guide provides an updated overview of NCM technologies, their classifications, and recent 2026 trends for use in professional presentations and industrial research. 1. Understanding Non-Conventional Machining
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: A high-speed gas stream carries abrasive particles to
Non-conventional processes are classified by the primary type of energy used to remove material: Energy Category Specific Process Mechanism of Material Removal Ultrasonic Machining (USM) Erosion by abrasive grains Abrasive Jet Machining (AJM) High-velocity abrasive impact Water Jet Machining (WJM) Fluid pressure erosion Thermo-Electric Electric Discharge Machining (EDM) Melting and vaporization via sparks Laser Beam Machining (LBM) Thermal melting and vaporization Plasma Arc Machining (PAM) High-temperature ionization and melting Chemical / Electrochemical Electrochemical Machining (ECM) Ion displacement (Anodic dissolution) Chemical Machining (CHM) Controlled chemical etching 2. Mechanical Advanced Machining Processes Ultrasonic Machining (USM)
Standard tools wear out instantly against materials like titanium, nimonics, and hardened steel.
The workpiece and a shaped tool electrode are submerged in a dielectric fluid (like kerosene or deionized water). A high-frequency pulsed DC voltage creates spark discharges across a microscopic gap. This intense spark vaporizes and melts the material. Critical Presentation Points:
