PRESS SYSTEM AND METHOD FOR CONTROLLING SAME

WIPO Patent Application WO/2019/049649

A1

A press system is provided with a press unit and a controller for controlling the press unit. The controller includes: a load pattern generating unit for generating a plurality of load patterns; an evaluation input unit for inputting a quality evaluation for each of a plurality of formed products formed by the press unit according to the plurality of load patterns; and an optimal load pattern setting unit for setting an optimal load pattern on the basis of a plurality of quality evaluations input by the evaluation input unit. The optimal load pattern setting unit has: a response surface generating unit that uses, as an objective function, evaluation value data when design variables are set for a load pattern to create a response surface for the objective function from evaluation value data based on a plurality of load patterns and a plurality of quality evaluations; and an optimization calculation unit that finds an optimal solution for the objective function for the response surface by optimization.
