Abstract
A motion generation device is configured to generate motion of a slide of a press device including the slide to which an upper die is attached, a bolster on which a lower die is placed, and a servomotor configured to move the slide reciprocally in the up and down direction. The motion generation device includes a motion generation section. The motion generation section is configured to generate a derivative motion of the slide at a cycle time different from the cycle time of the standard motion of the slide, such that the derivative motion includes the same motion as a first region of the standard motion including at least from top dead center to the end position of the molding region, and the speed of the slide at top dead center of the derivative motion is the same as the speed of the standard motion.
