A press machine includes: an electric motor for raising and lowering a slide by rotating a crank shaft; a motion datum receiving module through which, by an input operation, an operator inputs a motion datum including, as input items, height positions at which the slide starts and ends an oscillation process, a speed at which the slide carries out the oscillation process, an angle at which the crank shaft is rotated in a direction during a drive-in operation, and an angle at which the crank shaft is rotated in the other direction during a return operation; a motion pattern generator for generating a motion pattern of the slide on the basis of the motion datum inputted through the motion datum receiving module; and a motor controlling module for controlling the electric motor on the basis of the motion pattern generated by the generator.
