Abstract	This paper deals with an automated computer-aided process planning and die design system by which a designer can determine operation sequences even if they have only a little experience in process planning and die design for multi former-bolt products. The approach to the system is based on knowledge-based rules; a process knowledge base consisting of design rules is built. Knowledge for the system is formulated from plasticity theories, empirical results and the empirical knowledge of field experts. Programs for the system have been written in Auto LISP for the AutoCAD using a personal computer. An attempt is made to link programs incorporating a number of expert design rules with the process variables obtained by commercial FEM software, DEFORM and ANSYS, to form a useful package. The system is composed of four main modules. The process planning and the die design modules consider several factors, such as the complexities of perform geometry, punch and die profiles, the specifications of available multi former, and the availability of standard parts. They can provide a flexible process based on either the reduction in the number of forming sequences by combining the possible two processes in sequence, on the reduction of deviation of the distribution and the level of the required forming loads by controlling the forming ratios. As the system using 2D geometry recognition is integrated with the technology of process planning, die design, and CAE analysis, the standardisation of the die parts for multi former-bolt products requiring cold forging process is possible. The system developed will be useful in reducing the trial-and-error os design engineers in determining the diameter and height of the initial cylindrical billet from the final product geometry and the intermediate necessary sequence.
