Based on processing objectives and process characteristics, stamping operations are primarily categorized as follows:
Blanking: A stamping process that separates material; it involves cutting the desired part from the sheet along a closed contour or removing scrap material. Examples include blanking, punching, trimming, and cutting-off.
Bending: A stamping process in which sheet metal is bent along a straight line (bend line) to achieve a specific angle and shape, such as V-bending or U-bending.
Deep Drawing: A stamping process used to form sheet metal into an open, hollow part, or to further alter the shape and dimensions of an existing hollow part.
Forming: A stamping process that creates complex shapes in the workpiece through localized plastic deformation (including processes such as bulging, necking, flanging, and embossing).
