2. Snips - Wikipedia

   en.wikipedia.org/wiki/Snips

   In tinner's snips this means the handles are extra long. The compound-action bulldog-pattern, also known as a notch snips, has the ability to cut up to 16 gauge cold rolled sheet metal or multiple layers of sheet metal up to 0.062 in (1.6 mm) thick. Some snips have replaceable blades for when the blade becomes worn out.

3. Shear (sheet metal) - Wikipedia

   en.wikipedia.org/wiki/Shear_(sheet_metal)

   A power shear is electrically or pneumatically powered hand tool designed to blank large pieces of sheet metal. They are designed to cut straight lines and relatively large radius curves. They are advantageous over a bandsaw because there is not a size limit. Large versions can cut sheet metal up to 12 gauge. [5]

4. Sheet metal - Wikipedia

   en.wikipedia.org/wiki/Sheet_metal

   Sheet metal can be cut in various ways, from hand tools called tin snips up to very large powered shears. With the advances in technology, sheet metal cutting has turned to computers for precise cutting. Many sheet metal cutting operations are based on computer numerically controlled (CNC) laser cutting or multi-tool CNC punch press.

5. Types of press tools - Wikipedia

   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.

6. Die (manufacturing) - Wikipedia

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

   Steel-rule die, also known as cookie cutter dies, are used for cutting sheet metal and softer materials, such as plastics, wood, cork, felt, fabrics, and paperboard. The cutting surface of the die is the edge of hardened steel strips, known as steel rule. These steel rules are usually located using saw or laser-cut grooves in plywood.

7. Plasma cutting - Wikipedia

   en.wikipedia.org/wiki/Plasma_cutting

   Plasma cutting grew out of plasma welding in the 1960s, and emerged as a very productive way to cut sheet metal and plate in the 1980s. [1] It had the advantages over traditional "metal against metal" cutting of producing no metal chips, giving accurate cuts, and producing a cleaner edge than oxy-fuel cutting. Early plasma cutters were large ...
