Valery Marinov, Manufacturing Technology. 2.3 SHEET METALWORKING. Classification of Sheet Metalworking Processes. Basic sheet metalworking operations: (a) bending, (b) drawing, and (c) shearing; (1) as punch first contacts sheet and (2) after cutting. Force and relative motion are indicated by F Cutting and forming thin sheets of metal usually performed as cold working. • Sheet metal = 0.4 (1/64) to 6 mm (1/4in) thick. • Plate stock > 6 mm thick. • Advantage - High strength, good dimensional accuracy, good surface finish, economical mass production (low cost). • Cutting, bending, drawing ?. 2 ?. 1 ?. 1 ?. 3. ,?. 2. 2?. Shearing: Shearing of sheet metal between two cuDng edges: (1) just before the punch contacts work. (2) punch begins to push into work, causing plas&c deforma&on;. (3) punch compresses and penetrates into work causing a smooth cut surface;. (4) fracture is ini&ated at the opposing cuDng edges which separates the SHEET METAL WORKING. 1. Introduction. Sheet metal is simply metal formed into thin and flat pieces. It is one of the fundamental forms used in metalworking, and can be cut and bent into a variety of different shapes. Countless everyday objects are constructed of the material. Thicknesses can vary significantly, although Forming. • Trimming, flanging. • Springback. Most problems in sheet metal forming come from a bad control of holding, restraining and springback. Gravity fall. The blank adapts to . Further, based on the principle of conservation of Definition. In sheet metal forming practice, we distinguish five basic modes of deformation:. 1.1 Introduction: Sheet metal forming, also called stamping, involves operations such as cutting, drawing, spinning etc on sheets. Sheet metal forming involves predominantly tensile forces, compared to bulk forming, which involve compressive forces. Due to tensile stress, sheets may undergo localized deformation followed 2. Sheet Metal Cutting & Forming Processes. -General -. The raw material for sheet metal manufacturing processes is the output of the rolling process. Typically, sheets of metal are sold as flat, rectangular sheets of standard size. Therefore the first step in any sheet metal process is to cut the correct shape and sized 'blank' Sheet Metal Forming. • For products with versatile shapes and lightweight. • Dates to 5000 B.C.. • Products include metal desks, file cabinets, appliances, car bodies, beverage cans. • Common materials: low-carbon steel, aluminum or titanium. • First take sheet plate and cut into pieces by shearing, slitting, cutting, or sawing Sheet-Metal Forming.
