摘要

PROBLEM TO BE SOLVED: To predict in advance a damage risk portion of a cutting die used in a cutting process of press working, thereby easily taking efficient countermeasures against damage on a die and also reducing maintenance man-hours.SOLUTION: A method for predicting a damage risk portion of a cutting die includes: acquiring a product shape after cutting by performing cutting process analysis of a predetermined cutting position for a processing target shape; acquiring a product shape after spring back by performing spring back analysis for the acquired product shape after cutting; and comparing the product shape after cutting and the product shape after spring back, extracting a portion in the product shape after spring back which protrudes out from the predetermined cutting position of the product shape after cutting, and determining the protruding portion as a damage risk portion.
