The paper introduces a design method of CAPP, which is adopted in producing auto girders of various kinds and in great quantity. It puts forward a concept that the characteristic information -geometry and shape information are picked up according to graphic number of product and technological flow to provide the common information for designing of blanking, punching and bending. Thus,the production efficiency is enhanced and the technological requirement is met.
