Improvement of design technology and production of complex dies on the basis of modelling of process of their exploitation

The article presents results of design of complex dies in the manufacture of billets drilling of roller bits with guaranteed strength parameters on the basis of modeling their exploitation and applications of the theory of adaptability without conducting lengthy and expensive field experiments, as well as methods for finite element simulation of stamping process, which at the design stage and optimize models of stamps given the changeable power and temperature modes of operation, the geometric parameters of prints and choice of material.
