The conventional cold-heading process for the production of a bolt-shaped product is composed of some process and two or three blows heading. The strength of a bolt-shaped product produced by multi-blow heading depends on the working conditions of the heading process such as preforming die angle, corner-radius of the necked portion of product, and the reduction in height during pre-forming. Arigid-plastic finite-element program(RDHPSC) has been coded and the program testified by comparison with the results of experimentation. A method of testing the optimum die-conditions in the double-blow heading process by use of RDHPSC analysis is discussed a fundamental structures of CAD/CAPP system for two-blow heading process is discussed.
