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.
Metal forming tends to have more uniform characteristics across its subprocesses than its contemporary processes, cutting and joining.
This category of forming processes involves those operations where the primary means of plastic deformation involves both tensile stresses and compressive loads.
This category of forming processes involves those operations where the primary means of plastic deformation is a bending load.
This category of forming processes involves those operations where the primary means of plastic deformation is a shearing load.
