Introduction to NonTraditional Machining

examples of single action, mechanical non traditional machining processes • The machining medium is solid grains suspended in an abrasive slurry in the former,while a fluid is employed in the WJM process • The introduction of abrasives to the fluid jet enhances the machining efficiency and is known as abrasive water jet machining SimilarAn abrasive gun is used to supply an abrasive slurry, which is a mixture of abrasive grain and the water in between toolworkpiece interface under a definite pressure When the AC power is supplied with high frequency, the transducer starts vibrating longitudinally by magnetostriction, which is transmitted to the penetrating tool through aUltrasonic Machining: Parts, Working, AdvantageFor machining softer materials such as plastics and fibers simple water jet machining is used But when it comes to harder materials such as metals, water alone cannot provide satisfactory results Hence Abrasive particles are mixed with the water jet to perform the cutting action This process is known as Abrasive water jet machiningWater Jet Machining: Definition, Working Principle

Machining Wikipedia

Machining is a process in which a material (often metal) is cut to a desired final shape and size by a controlled materialremoval process The processes that have this common theme are collectively called subtractive manufacturing, in contrast to additive manufacturing, which uses controlled addition of materialExactly what the "controlled" part of the definition implies canA water jet cutter, also known as a water jet or waterjet, is an industrial tool capable of cutting a wide variety of materials using an extremely highpressure jet of water, or a mixture of water and an abrasive substance The term abrasive jet refers specifically to the use of a mixture of water and abrasive to cut hard materials such as metal, stone or glass, while the terms pure waterjetWater jet cutter WikipediaOct 24, 2015· In the machining system shown in Fig 32, the wheel is a rotating cathodic tool with abrasive particles (60–320 grit number) on its periphery Electrolyte flow, usually NaNO3, is provided for ECDAdvanced Manufacturing Processes PDF Full book by badebhau
