Abstract
A method is proposed to solve the joint optimization problem based on system quality criteria for the thermophysical processes of preheating and subsequent plastic deformation of metal semi-finished products in industrial metal working systems with a free choice of the admissible initial temperature states before plastic deformation that integrate these processes in a single process system. Potentials for practical applications of the method is illustrated by the example of a process system for forming pressed articles from aluminum alloys.
