Non Conventional Machining Process Ppt | Updated ~repack~

The manufacturing landscape is evolving rapidly. As materials get tougher (think Titanium alloys, Inconel, Ceramics, and Composites), traditional lathes and milling machines hit their limits.

Non-Conventional Machining (NCM) processes—also known as Advanced Machining Processes (AMP)—remove material without direct mechanical contact or conventional cutting tools. Instead, they utilize thermal, chemical, electrical, or high-velocity mechanical energy.

A variation of EDM that uses a continuously moving thin wire (typically brass or copper, 0.1 mm to 0.3 mm diameter) as the electrode. The wire acts like a bandsaw, cutting precise 2D and 3D profiles through a conductive workpiece.

The tool does not touch the workpiece; it impacts the abrasive grains. The manufacturing landscape is evolving rapidly

ECM removes material by anodic dissolution in an electrolyte bath under an applied voltage. The process is stress-free, produces a burr-free and mirror-like surface finish, and does not cause thermal damage. ECM excels in machining high-strength alloys and delicate features that require precision without tool degradation, and is often applied in the production of turbine blades and components with complex geometries. The wire acts like a bandsaw, cutting precise

These processes utilize localized thermal energy to melt, vaporize, or fuse the workpiece material. Electric Discharge Machining (EDM) & Wire-EDM Laser Beam Machining (LBM) Electron Beam Machining (EBM) Plasma Arc Machining (PAM) D. Chemical Energy Processes

Each process description in your PPT should be a balanced mix of theory and application. Here is the essential information to include for several major processes.

Extrusion dies, punch-and-die sets, and intricate gears. Electrochemical Machining (ECM)
