Forging is defined a s the process in which metal is plastically deformed with application of temperature and pressure. It is used to change not only the shape but also the properties of the metal because it refines the grain size and therefore improves its structure. Forging is a cost-effective way to produce net-shape or near-net -shape components. Forged parts are used in high performance

sheet metal forming processes. Bending, stretching and drawing of simple shapes are analysed, as are certain processes for forming thin-walled tubing. Where possible, the limits governing each process are identified and this entails a detailed study of tensile instability in thin sheet. To the authors’ knowledge, this is the first text in English to gather together the mechanics of sheet

Aerospace metal forming technologies ARIES ALLIANCE SHAPING A BETTER FUTURE 3. SHEET STRETCH FORMING Sheet Stretch Forming is a fast, economical, and accurate way to form a large panel from a metal sheet. The process involves stretching the sheet to a calculated yield point and forming it over a tool. Transverse Sheet Stretch Forming Press (FET/T) Up to 12 independently …
normal forming processes, but on the contrary, there are certain limitations also. So, these advantages and limitations have to be studied before we go and choose a high energy rate forming process to convert our raw sheet of metal into our final product.
Velocity Forming (HVF) processes. • Many metals tend to deform more readily under extra fast application of force. • Large parts can be easily formed by this technique.
This process of thinning of the cup wall is called ironing.NPTEL . Friction due to hold down pressure as well as sliding tends to increase reach a peak value and decreases early during the drawing. which is getting pressed by the punch bottom. punch geometry.

Abstract. The type of lubrication regime which occurs in a metal forming operation has a strong influence on the frictional conditions as well as on other important factors such as product surface finish and tooling wear rates.
The common sheet metal forming products are metal desks, file cabinets, appliances, car bodies, aircraft fuselages, mechanical toys and beverage cans and many more. Due to its low cost and generally good strength and formability characteristics, low carbon steel is the most commonly used sheet metal because high carbon composition gives high strength to the material. The other sheet metals

Nowadays the engineering and planning process in sheet metal forming is fundamentally supported by CAD and CAE systems. Beside the full 3D design process of parts and tools the simulation of sheet metal forming processes has established itself in the last 15 years within standard industrial practises. Nevertheless the virtual engineering and planning consists of more than just CAD and CAE
