Introduction:
Sheet Metal Forming is a process of making a flat sheet metal into a desired shape part without excessive localized thinning or Fracture.
This following report on sheet metal forming consists of forming study of two components one given in the course and an another outside of our field of work, it details the materials used and their metallurgical properties and alternative materials that can be considered. Detail the forming process used and an alternative route. Also Detail the forming effects such as spring back and the methods to reduce them.

Mechanical properties of metals:
Formability is the ease with which the sheet metal can be shaped through plastic deformation
Parts, when in service and while forming, are subjected to forces. It is necessary to know the characteristics of the material to design and form the component so that any resulting deformation will not result in failure of the component in service and while forming.
These characteristics of material can be determined by stress strain tests using a test sample, one of the most common is tensile test, which measures two types of mechanical properties 1.Strength properties: yield strength, Modulus of elasticity, Ultimate tensile strength. 2. Ductile properties: percentage of elongation
Deformation of a material or strains depends on the magnitude of stress. For most metals that are stressed in tension stress and strain are proportional Deformation at which stress is proportional to stain is called elastic deformation, a plot of stress versus strain results in a linear relationship. The slope of this linear segment represents to the modulus of elasticity E. This modulus indicates the stiffness of the material or material’s resistance to el...

Incremental Sheet Metal Forming Essay

- INCREMENTAL SHEET METAL FORMING Introduction Incremental Sheet Metal Forming (ISMF) is a technique used to shape sheet metal and is usually used for rapid prototyping. The process begins with sheet metal secured below the ISMF device’s main body. A metal rod, which can be either a ball, a rounded shape or a cube is lowered onto the sheet metal and traced over the material in the desired shape. Computer software is used to create the desired product and trail paths are mapped before the process begins....   [tags: technique for rapid prototyping]

Sheet Metal Forming: Springback Control Essay

- I. SPRING BACK CONTROL AND ACTIVE CONTROLS OF SPRINGBACK Abstract The forming of sheet metal requires an understanding of a wide range of technical knowledge, the manufacturing application criterion and the interaction of processing and the material's properties. One of the major causes of inconsistent parts is springback, which Hu, Marciniack and Duncan define as the elastic strain recovery in the material after the tooling is removed (2002). This paper delineates an experiment carried out by Vikram Viswanathan (Northwestern University), Brad Kinsey (University of New Hampshire) and Jian Cao (Northwestern University) titled "Experimental Implementation of Neural Network Springback Control...   [tags: Engineering]

The Process of Designing a Truck Bed Essay

- Summary The objective for this lab was for each individual to make a truck bed from a 1010 steel metal sheet. The individual would learn the process of bending the the metal, designing a shape based on dimensions, and shearing off parts that lack purpose in the design. This process of designing the truck bed takes time, precision, and carefulness. From this process one learns the basics of forming, and all the basic equipment required to create a truck bed. Introduction Modern day manufacturing provides us with a vast array of metal forming processes to choose from....   [tags: steel metal sheet, shearing, blanking]

Jewelry Making: Hydraulic Die Forming Essay

- Die-forming of sheet metal has been around for thousands of years. Originally the metal was manipulated by hand and hammered into the depression, by utilizing crude grooves carved into wood or stone. This technique was used to make spouts, handles, and other forms. Since then, however; they have undergone a remarkable technological evolution. Mate-female conforming dies to create hollow forms by using hydraulic pressure or drop hammer pressure, changed die-forming forever (Paisin, 2013). This new form was called hydraulic die-forming....   [tags: sheet metal shaping technique]

Single Point Incremental Forming Essay

- Introduction For centuries, man has been producing sheet metal components using different tools and techniques. A method universally applied is the use of dies and punches, manufactured in accordance with the shape and dimensions of the component. However, despite being widespread, it contains technological hindrances, such as large energy costs and very high investment, which make this process very expensive. Because of the high cost of punches and dies, this method is only suitable for mass production, where the cost can be shared with a large number of products....   [tags: Scientific Research ]

The Process of Gas Metal Arc Welding Essay

- Gas metal arc welding, or most commonly referred to as MIG welding is a very common and sometimes preferred method of welding. Gas metal arc is personally one of the easiest and controllable welding types there is. Gas metal arc welding was originally made for weld materials such as aluminum, copper, brass, tin and lead. It was also used on steels, but shielding gases were highly expensive in the early 1900s limiting GMAW’s use on steel. It wasn’t till the mid 1900’s for GMAW to really take off....   [tags: process]

Why We Use Metal Sheets Essay

- For as long as people have had the means, metal has been beaten into sheets and used for architectural purposes, from roof coverings to sewer pipes. In the late seventeenth century, this hand-hammering process was later replaced by large “rotating iron cylinders” which pressed metal into flattened sheets (Simpson 31). These water-powered rolling mills allowed for more uniform sheets as well as a less laborious and time-consuming process. The sheets were allowed to be thinner, which was advantageous when creating smaller details, such as gutters and roofing....   [tags: Installation, Metal Types, Architecture]

The Metal Of Metal Music Essay

- ... Behemoth has the satanic and murderous lyrics while Mayhem is known for their violent stage performances given at their concerts. Both also have huge controversies, a major one for Behemoth would be that they were banned from Russia in the year of twenty-fourteen due to implications of the band promoting murder and satanism. Mayhem’s biggest controversy was that they wanted to wear makeup that made them appear to be actual corpses, nothing like the makeup of the band Kiss for example. Dead, the band 's vocalist, would entomb the clothes he wore for his stage performances and dig them back up to wear for that night 's concert in order to complete his overall image of a corpse....   [tags: Heavy metal music, Black metal]

The Turner Frontier in Full Metal Jacket” Essay

- In Stanley Kubrick’s “Full Metal Jacket”, Turner’s Frontier is presented within the confines of Vietnam and shows the frontier in all of its brutality. Unlike other western style movies, which romanticise the frontier, Kubrick openly attacks the Turner Frontier myths, stating that rather than stripping the frontiersmen down and reforming them as the ideal example of American society, the Turner mindset, of completely stripping away one’s culture, actually transforms the frontiersmen into childlike figures, who are unable to think for themselves....   [tags: Stanley Kubrick, Full Metal Jacket]
