2. Drawing (manufacturing) - Wikipedia

   en.wikipedia.org/wiki/Drawing_(manufacturing)

   Successful drawing depends on the flow and stretch of the material. Steels, copper alloys, and aluminium alloys are commonly drawn metals. [4] In sheet metal drawing, as a die forms a shape from a flat sheet of metal (the "blank"), the material is forced to move and conform to the die. The flow of material is controlled through pressure applied ...

4. Tailored blank - Wikipedia

   en.wikipedia.org/wiki/Tailored_blank

   Tailored blanks are semi-finished parts, which are typically made from sheets with different alloys, thicknesses, coatings or material properties. After joining, these will be subjected to deep drawing or stamping. Tailored blanks were developed by ThyssenKrupp to make sheets that were wider than those made on available rolling mills of the ...

   [citation needed] Along with these reasons, lancing is also used to make tabs (where the material is bent at a 90-degree angle to the material), vents (where the bend is around 45 degrees), and louvers (where the piece is rounded or cupped). [citation needed] Lancing also helps to cut or slight shear of sheet on cylindrical shape. [citation needed]
