Adhesion prediction method, adhesion prediction program, and adhesion prediction device

A non-transitory computer-readable storage medium storing an adhesion prediction program for predicting an adhesion of metal particles in a workpiece to a die in a forging process using an aluminum-based material as the workpiece, the adhesion prediction program causing a computer to execute:

• an input process of receiving computer-aided design (CAD) information from a CAD device and various conditions that are used for analysis from an input device;
• a cumulative friction work amount calculation process of calculating a cumulative friction work amount generated between the workpiece and the die;
• a metal diffusion analysis process of analyzing a diffusion state of the metal particles between the workpiece and the die;
• an adhesion prediction determination process of predicting a state of an occurrence of the adhesion of the metal particles to the die, considering the cumulative friction work amount calculated in the cumulative friction work amount calculation process, the diffusion state analyzed in the metal diffusion analysis process, and a film thickness of a lubricating film provided on a surface of the die that comes into contact with the workpiece, the metal particles being of the aluminum-based material;
• and
• outputting an analysis model of the occurrence of the adhesion.
