Abstract
An adhesion prediction method of predicting adhesion of metal particles in a workpiece to a die in a forging process using an aluminum-based material as the workpiece includes: a cumulative friction work amount calculation step of calculating a cumulative friction work amount generated between the workpiece and the die; a metal diffusion analysis step of analyzing a diffusion state of the metal particles between the workpiece and the die; and an adhesion prediction determination step of predicting a state of 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 step, the diffusion state analyzed in the metal diffusion analysis step, and a film thickness of a lubricating film provided on a surface of the die that comes into contact with the workpiece.
