Non Conventional Machining Process Ppt Jun 2026

Uses ultrasonic vibrations and an abrasive slurry.

Slicing weight-reduction pockets into large aerospace wing panels (Chemical Milling).

First, Elias experimented with the Mechanical approach. He didn't use a drill bit; he used sound and water.

Ultrasonic Machining is a non-thermal, non-chemical, and non-electrical mechanical process. It is highly effective for machining brittle and hard materials. Non Conventional Machining Process Ppt

Advanced Manufacturing Techniques for Modern Materials

Requires substantial energy input per unit volume of material removed.

Developing biodegradable dielectric fluids (like vegetable-based oils) and safer electrolytes to minimize the environmental footprint of these manufacturing units. Uses ultrasonic vibrations and an abrasive slurry

As electronics, medical devices, and aerospace systems shrink, variants like Micro-EDM and Femtosecond Laser Beam Machining are leading the production of micro-fluidic chips and vascular stents.

Capable of machining materials irrespective of their hardness or strength.

Zero tool wear, excellent surface finish, high material removal rate regardless of hardness. He didn't use a drill bit; he used sound and water

With Electrochemical Machining (ECM) , they used electricity to dissolve metal atom by atom, creating smooth finishes for intricate injection molds that a physical drill could never touch. The New Standard

Another crucial trend covered in PPTs is the integration of with non-conventional processes. This marriage of technologies allows for greater accuracy, repeatability, and the ability to produce highly complex 3D shapes automatically. PPTs often include notes on how adaptive control machining becomes easier with these advancements, enhancing the overall volumetric material removal rate and performance.

To create complex shapes that are impossible with traditional tools. To achieve high surface finish and precision. Slideshare 2. Comparison: Conventional vs. Non-Conventional Conventional Machining Non-Conventional Machining Tool Material Must be harder than the workpiece. Tool hardness is not a primary requirement. Tool Contact Direct physical contact with the workpiece. No physical contact; energy is transferred instead. Material Removal Plastic deformation/chipping. Erosion, melting, or chemical dissolution. Noise & Waste High noise and physical scrap. Generally quieter and more precise. 3. Classification of NCM Processes

Mastering Non-Conventional Machining Processes: The Ultimate Technical Overview

Spark erosion occurs in a localized path between an electrode (tool) and a conductive workpiece.
