Manufacturing Process and Optimization

A computer-aided process design system for axisymmetric deep drawing products has been developed. An approach to the CAD system is based on a knowledge-based system, the knowledge for the CAS system being formulated from plasticity theories, handbooks, experimental results and the empirical knowledge of field experts. The CAD system has been written in AutoLISP on the AutoCAD system with a personal computer. The CAD system is composed of four main modules, which are input, geometrical design, test and rectification and user modification. The input to the system is the drawing of the final sheet-metal object geometry and the output from the system is the drawing of process sequence with intermediate object geometry and the drawing of the process parameters, such as the drawing load, the blank-holding force, the clearance and the cup-drawing coefficients. The developed CAD system will aid designers by providing powerful capabilities for the process design of axisymmetric deep-drawing products.
