  2. Cold working - Wikipedia

    en.wikipedia.org/wiki/Cold_working

    In metallurgy, cold forming or cold working is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature.. Such processes are contrasted with hot working techniques like hot rolling, forging, welding, etc. [1]: p.375 The same or similar terms are used in glassmaking for the equivalents; for example cut glass is made by "cold ...

  3. Tube bending - Wikipedia

    en.wikipedia.org/wiki/Tube_bending

    Tube bending is any metal forming processes used to permanently form pipes or tubing. Tube bending may be form-bound or use freeform-bending procedures, and it may use heat supported or cold forming procedures. Form bound bending procedures like “press bending” or “rotary draw bending” are used to form the work piece into the shape of a ...

  4. Bending - Wikipedia

    en.wikipedia.org/wiki/Bending

    In the absence of a qualifier, the term bending is ambiguous because bending can occur locally in all objects. Therefore, to make the usage of the term more precise, engineers refer to a specific object such as; the bending of rods, [2] the bending of beams, [1] the bending of plates, [3] the bending of shells [2] and so on.

  5. Rolling (metalworking) - Wikipedia

    Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property.

    In Western cultures, it is often considered proper for women to perform a curtsey by bending the knees instead of a bow. Genuflection (or genuflexion) is bending at least one knee to the ground, was from early times a gesture of deep respect for a superior. Kneeling is associated with reverence, submission and obeisance.

  7. Bending (metalworking) - Wikipedia

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

    Bending A chimney starter, a sample product of bending. Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. [1] Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses.

  8. Steam bending - Wikipedia

    en.wikipedia.org/wiki/Steam_bending

    Steam bending is limited in the degree of bend it can achieve, particularly for thick wood. Also, not all species of wood steam-bend well. [2] It weakens the wood slightly and can leave residual stresses which may cause breakage, blowouts or spring-back over time. To properly bend a sheet or plank of wood, there are a few techniques that will help.

    Illustration of a woman raising her dress and mooning a nun (1905) Mooning is the act of displaying one's bare buttocks by removing clothing, e.g., by lowering the backside of one's trousers and underpants, usually bending over, and also potentially exposing the genitals.
