Non Conventional Machining Process Ppt
Cutting surgical stents and manufacturing orthopedic implants (Wire EDM).
Excellent for miniaturized components in electronics and medical devices. 4. Applications of NCM Processes
Easily shapes materials like tungsten carbide, diamond, titanium, and advanced ceramics.
(lower material removal rate) than a giant CNC mill. They also require high initial investment
Traditional machining methods like turning, milling, and drilling remove material using a tool that is harder than the workpiece. However, modern engineering demands the use of high-strength, brittle, and heat-resistant materials like titanium, ceramics, and superalloys. Non Conventional Machining Process Ppt
Machining brittle materials like glass, ceramics, quartz, and precious stones.
The tool and workpiece rarely make physical contact, eliminating tool wear from friction.
DC power supply, tool electrode (brass/copper/graphite), dielectric fluid (kerosene/deionized water), servo system.
Uses a high-velocity jet of ionized gas (plasma) to melt and blow away conductive metals. 3. Chemical and Electrochemical Processes Applications of NCM Processes Easily shapes materials like
Non-Conventional Machining (NCM) processes, also known as Non-Traditional Machining (NTM), represent a group of material removal processes that do not use traditional sharp cutting tools or direct physical contact between a tool and a workpiece to remove material
Material is removed by a rapid series of recurring electrical spark discharges between a shaped tool (cathode) and a conductive workpiece (anode) immersed in a dielectric fluid (like kerosene or deionized water). The intense heat melts and vaporizes the material.

This paper provides a high-level overview of Non-Traditional Machining (NTM) Advantages: Low capital cost
Deburring, cleaning surfaces, cutting thin sheets of glass or ceramics. Advantages: Low capital cost; no heat-affected zone. Thermal: Electrical Discharge Machining (EDM)
Unlike traditional machining, NCM does not require a physical tool that is harder than the workpiece, and there is often no direct contact between the tool and the part. Why use NCM?
For a presentation on Non-Conventional Machining (NCM) , you can structure your content into these key sections. NCM refers to material removal processes that use energy sources like thermal, chemical, or electrical power instead of direct physical contact with a sharp tool.
