Abstract
Bending is a common metalworking operation to create localized deformation in sheets (or blanks), plates, sections, tubes, and wires. This article emphasizes on the bending of sheet metal along with some coverage on flanging. It informs that variations in the bending stresses cause springback after bending, and discusses the variables and their effects on springback, as well as the methods to overcome or counteract them. These methods include overbending, bottoming or setting, and stretch bending. The article provides information on elastic bending, non-cylindrical bending, elastic-plastic bending, and pure plastic bending. Sheet metal bendability is a critical factor in many forming operations. The article illustrates the derivation of two relevant bend-ductility equations.

Abstract
The multiple-slide machine, sometimes called a four-way, four-slide, or multislide machine, is a somewhat specialized item of stamping equipment, although it is very versatile within a limited area of stamping applications. This article discusses the construction and advantages of multiple-slide machines. It presents comparisons of four-slide operations with press operations based on production speed, tooling cost, tool adjustments, and operating cost. The article reviews some factors to be considered while selecting multiple-slide machines. It summarizes the strip materials commonly used in four-slide production. The article examines the design factors of four-slide parts, including tolerances and finishes. It provides the design recommendations for optimal part quality at maximum production speed. The article also discusses various four-slide cutoff methods.

Abstract
This article discusses the general formability considerations of aluminum alloys. To conduct a complete analysis of a formed part, the required mechanical properties, as determined by several standard tests, must be considered. The article describes tension testing and other tests designed to simulate various production forming processes, including cup tests and bend tests, which help in determining these properties. It provides information on the equipment and tools, which are used in the forming of aluminum alloys. The article presents a list of lubricants that are most widely used in the forming. It also analyzes the various forming processes of aluminum alloys. The processes include blanking and piercing, bending, press-brake forming, contour roll forming, deep drawing, spinning, stretch forming, rubber-pad forming, warm forming, superplastic forming, explosive forming, electrohydraulic forming, electromagnetic forming, hydraulic forming, shot peening, and drop hammer forming.

Abstract
This article discusses the types and operations of the most common machines used for die threading. The construction, types, and comparison of solid and self-opening dies are discussed. The article explains the modification of chasers for threading Monel shaft. The principal factors that influence thread quality, production rate, and cost in die threading are composition and hardness of work metal; accuracy and finish; thread size; obstacles, such as shoulders or steps; speed; lead control; and cutting fluid. The article examines these factors and describes the tools and cutting fluids used for pipe threading along with the severity of stop lines.

Abstract
Simulation programs are becoming more effective tools in reducing the need for physical testing and the avoidance of costly downstream problems by solving the problems upfront in the early development stage. This article provides a brief review of the history and applied analysis of simple forming operations. It focuses on metal stamping simulation based on the finite-element methods or model (FEM) with emphasis on software tools using the three-dimensional FEM technology. The article discusses two aspects of particular importance in finite-element analysis of sheet forming and springback analysis: the type of solution algorithm/governing equation and the type of element. The article provides information on various models for material yield criteria.
