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 gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.
Blanking is the operation of cutting flat shapes from sheet metal. The outer area of metal remaining after a blanking operation is generally discarded as waste. Size of blank or product is the size of the die & clearance is given on punch. It is a metal cutting operation. In blanking, metal obtained after cutting is not a scrap if it is usable.
Drawing is a manufacturing process that uses tensile forces to elongate metal, glass, or plastic. As the material is drawn (pulled), it stretches and becomes thinner, achieving a desired shape and thickness. Drawing is classified into two types: sheet metal drawing and wire, bar, and tube drawing.
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.
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. — Preceding unsigned comment added by 134.24.147.249 ( talk ) 12:38, 29 January 2015 (UTC) [ reply ]
(Glare1 can only consist of aluminum layers of 0.3 to 0.4 mm (0.012 to 0.016 in; 12 to 16 mils) thickness, though.) For example, Glare4B-4/3-0.4 is a Glare sheet with a Glare4 grade (using the B variant) where there are four aluminum layers and three glass fiber layers, and the thickness of each aluminum layer is 0.4 mm (0.016 in; 16 mils).
