Few Aspects in Deep Drawing Process

D Swapna, S Radhika, Ch. Srinivasa Rao


The process in which a punch forces a flat sheet metal blank into a die cavity is known as deep drawing. Deep Drawing (DD) is one of the sheet metal forming processes widely used in automobile, aerospace, electronics and allied industries to produce the hollow parts. Presently, the conventional deep drawing (CDD) operation is carried out at room temperature in industries. Although, CDD provides a great potential application for the manufacturing of parts with complex shapes, CDD becomes a difficult process for smaller dimensioned parts.  For a decreasing specimen size, the major problem is the scaling effect which is a result of increased friction coefficient. An attempt has been made in the present paper to study few aspects of DD processes currently being followed.
