METHOD FOR PREDICTING WEAR AND LIFESPAN OF PRESS TOOL BY USING WEAR MODEL

摘要

A method for predicting the wear of a press tool comprises the steps of: calculating an abrasive wear amount of the press tool by applying an abrasive wear model to a finite element analysis simulation program; calculating a fatigue wear amount on the basis of a difference between the abrasive wear amount and an actually measured wear amount obtained by performing an actual press process using the press tool; and calculating a wear amount of the press tool by applying, to the finite element analysis simulation program, an abrasive wear model in which the abrasive wear amount is reflected and a fatigue wear model in which the fatigue wear amount is reflected, and using a wear simulation of the press tool.
