  2. Cutting stock problem - Wikipedia

    en.wikipedia.org/wiki/Cutting_stock_problem

    Cutting stock problem. In operations research, the cutting-stock problem is the problem of cutting standard-sized pieces of stock material, such as paper rolls or sheet metal, into pieces of specified sizes while minimizing material wasted. It is an optimization problem in mathematics that arises from applications in industry.

  3. Sheet metal forming simulation - Wikipedia

    en.wikipedia.org/wiki/Sheet_metal_forming_simulation

    Sheet metal forming, which is often referred to as stamping, is a process in which a piece of sheet metal, referred to as the blank, is formed by stretching between a punch and a die. The most painful and most frequent defects are wrinkles, thinning, springback and splits or cracks. Few methods are being used around the industry to cope with ...

  4. Stamping (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Stamping_(metalworking)

    Stamping (metalworking) Animation of a power press with a fixed barrier guard. Stamping (also known as pressing) is the process of placing flat sheet metal in either blank or coil form into a stamping press where a tool and die surface forms the metal into a net shape. Stamping includes a variety of sheet-metal forming manufacturing processes ...

  5. Forming (metalworking) - Wikipedia

    en.wikipedia.org/wiki/Forming_(metalworking)

    Forming (metalworking) In metalworking, forming is the fashioning of metal parts and objects through mechanical deformation; the workpiece is reshaped without adding or removing material, and its mass remains unchanged. [1] Forming operates on the materials science principle of plastic deformation, where the physical shape of a material is ...

  6. Sheet metal forming analysis - Wikipedia

    en.wikipedia.org/wiki/Sheet_metal_forming_analysis

    Sheet metal forming analysis. For sheet metal forming analysis within the metal forming process, a successful technique requires a non-contact optical 3D deformation measuring system. The system analyzes, calculates and documents deformations of sheet metal parts, for example. It provides the 3D coordinates of the component's surface as well as ...

  7. Shop drawing - Wikipedia

    en.wikipedia.org/wiki/Shop_drawing

    A shop drawing is a drawing or set of drawings produced by the contractor, supplier, manufacturer, subcontractor, consultants, or fabricator. [1] Shop drawings are typically required for prefabricated components. Examples of these include: elevators, structural steel, trusses, pre-cast concrete, windows, appliances, cabinets, air handling units ...

  8. Forming limit diagram - Wikipedia

    en.wikipedia.org/wiki/Forming_limit_diagram

    A forming limit diagram, also known as a forming limit curve, is used in sheet metal forming for predicting forming behavior of sheet metal. [1][2] The diagram attempts to provide a graphical description of material failure tests, such as a punched dome test. In order to determine whether a given region has failed, a mechanical test is performed.

  9. Incremental sheet forming - Wikipedia

    en.wikipedia.org/wiki/Incremental_sheet_forming

    Incremental sheet forming. Incremental sheet forming (or ISF, also known as Single Point Forming) is a sheet metal forming technique where a sheet is formed into the final workpiece by a series of small incremental deformations. However, studies have shown that it can be applied to polymer and composite sheets too.
