The sizing operation is a squeezing operation that minimizes the thickness of the metal. Sizing is performed in an open die and only the surface where the die and workpiece touch will be sized. Many ferrous metal castings are sized to sharpen corners and flatten holes around piercings. Sizing pressure is determined by area to be sized, the ...
Solid “bridging” to stabilize floor joists. Blocking placed as attachment points for cabinets, while doubling as bracing against compression of the studs. Blocking (dwang, nog, noggin, and nogging) is the use of short pieces of dimensional lumber in wood framed construction to brace longer members or to provide grounds for fixings.
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.
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 metalworking, forming is the fashioning of metal parts and objects through mechanical deformation; the workpiece is reshaped without adding or removing material, and its mass remains unchanged. [1] Forming operates on the materials science principle of plastic deformation, where the physical shape of a material is permanently deformed.
Crimp tool for 0.14 mm 2 to 10 mm 2 (26–8 AWG) insulated and non-insulated ferrules. Crimping is a method of joining two or more pieces of metal or other ductile material by deforming one or both of them to hold the other.
Wood wall panelling has seen a resurgence in popularity in recent years due to its aesthetic appeal, versatility, and sustainability. Traditionally used to insulate and decorate interiors, modern wood panelling includes wainscoting, beadboard, shiplap, board and batten, and both raised and flat panels. This renewed interest is driven by the ...
Today the metal forming industry is making increasing use of simulation to evaluate the performing of dies, processes and blanks prior to building try-out tooling. Finite element analysis (FEA) is the most common method of simulating sheet metal forming operations to determine whether a proposed design will produce parts free of defects such as fracture or wrinkling.
