The basis for a design support system to prevent defects in forging

Abstract The present paper describes the basis for a system to reduce the number of defects in a forged component. For this purpose two classifications are created as originally suggested by Dodd. The first divides the possible defects into six groups and the second classifies the probable causes of the defects. By use of these classifications, a catalogue showing the relation between the defects and their causes is established. This catalogue, called the Defect-Matrix, can be created for all types of forging processes and workpiece geometries as a valuable aid for the designer.
