Abstract
A press machine includes a controller including a displacement calculator being adapted to calculate a slide displacement with a slide being kept at a waiting position displaced from a top dead center by an amount corresponding to a predetermined crank angle based on a measured value of a pre-adjustment die height provided for a height adjustment of the slide, a desired value of a post-adjustment die height, the crank angle, a distance between an upper surface of a bolster and a crank center of an eccentric portion, a crank radius of the eccentric portion, and a distance between a lower surface of the slide and a point center, thereby associating the slide displacement with a difference between the pre-adjustment die height and the post-adjustment die height.
