  2. Sheet metal - Wikipedia

    en.wikipedia.org/wiki/Sheet_metal

    Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its ...

  3. Engineering drawing abbreviations and symbols - Wikipedia

    en.wikipedia.org/wiki/Engineering_drawing...

    A list, usually tabular and often on the drawing (if not accompanying the drawing on a separate sheet), listing the parts needed in an assembly, including subparts, standard parts, and hardware. There is no consistently enforced distinction between an L/M, a BoM, or a P/L. PLM: product lifecycle management; plant lifecycle management: See also ...

    There are several errors in the thickness and tolerance charts. e.g. the nominal thickness for stainless steel 16ga sheet should be .0625". The thickness ranges is the tolerance chart do not line up properly with the gauge column and the values are not in agreement with the thickness chart.

  5. Bending (metalworking) - Wikipedia

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

    In bottoming, the sheet is forced against the V opening in the bottom tool. U-shaped openings cannot be used. Space is left between the sheet and the bottom of the V opening. The optimum width of the V opening is 6 T (T stands for material thickness) for sheets about 3 mm thick, up to about 12 T for 12 mm thick sheets.

  6. Standard wire gauge - Wikipedia

    en.wikipedia.org/wiki/Standard_wire_gauge

    A standard wire gauge. British Standard Wire Gauge (often abbreviated to Standard Wire Gauge or SWG) is a unit for denoting wire size given by BS 3737:1964 (now withdrawn). It is also known as the Imperial Wire Gauge or British Standard Gauge.

    Similarly, two sheets of A4 can be scaled down to fit one A4 sheet without excess empty paper. This system also simplifies calculating the weight of paper. Under ISO 536 , paper's grammage is defined as a sheet's mass in grams (g) per area in square metres (unit symbol g/m 2 ; the nonstandard abbreviation "gsm" is also used). [ 5 ]

  8. Rolling (metalworking) - Wikipedia

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

    For thin sheet metal with a thickness less than 200 μm (0.0079 in), [citation needed] the rolling is done in a cluster mill because the small thickness requires a small diameter rolls. [10] To reduce the need for small rolls pack rolling is used, which rolls multiple sheets together to increase the effective starting thickness.

  9. Ultrasonic thickness measurement - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_Thickness...

    The ability to gauge thickness measurement without requiring access to both sides of the test piece, offers this technology a multitude of possible applications. Paint thickness gauges, ultrasonic coating thickness gauges, digital thickness gauges and many more options are available to test plastics, glass, ceramics, metal and other materials.
