Non Conventional Machining Process | Ppt Updated
: Material is removed by a rapid series of recurring electrical spark discharges between a shaped tool (cathode) and the workpiece (anode), completely immersed in a dielectric fluid (like hydrocarbon oil or deionized water). Each spark generates localized temperatures up to 12,000°C, melting and vaporizing the material.
These processes use localized thermal energy to melt, vaporize, or fuse material away.
Offers superior surface integrity, often eliminating the need for post-processing. 2. Classification of Non-Conventional Machining Processes non conventional machining process ppt updated
Non-conventional machining processes do not replace conventional methods; they complement them when traditional methods reach their physical limits.

Non-Conventional Machining Processes: The Ultimate Overview Traditional manufacturing methods like turning, milling, and drilling rely on physical contact between a sharp cutting tool and a workpiece. This mechanical friction creates significant heat and stress, which fails when processing extremely hard, brittle, or ultra-thin materials. A specific type of EDM that uses a
Non-conventional machining refers to a group of material removal processes that do not use sharp cutting tools or physical shear forces. Instead, they leverage advanced energy domains to erode, melt, vaporize, or chemically dissolve unwanted material.
