Abstract: Disclosed herein is a technique to efficiently pack a print volume of 3D printers having print jobs with a large number of objects. The technique positions unique objects that adhere to a similar structural pattern more closely when the degree of variation between the objects is small. Thus, while each object is unique, a greater extent of similarity between the objects causes a given group of objects to be positioned more closely to one another in the print area of the 3D printer.

Further, in the case of a state in which a press operation in punch press machining is started from a different position from a position of a preset rising edge, an overlap time is calculated based on a position of a punch head when the press operation is started, and an output timing of interpolation data related to an axis controlling the press operation is controlled based on the calculated overlap time. In this way, even when there is a change in press stroke, a dead time may be prevented from being generated.
