Press working is used as general term to cover all press working operations on sheet metal. The stamping of parts from sheet metal is shaped or cur through deformation by shearing, punching, drawing, stretching, bending, coining etc. Production rates are high and secondary machining is not required to produce finished parts with in tolerance.

A pressed part may be produce by one or a combination of three fundamental press operations. They include:

• Cutting (blanking, piercing, lancing etc) to a predetermined configuration by exceeding the shear strength of the material.
• Forming (drawing or bending) whereby the desired part shape is achieved by overcoming the tensile resistance of the material.
• Coining (compression, squeezing, or forging) which accomplishes surface displacement by overcoming the compressive strength of the material.
