Motion setting method for transfer press and transfer press

A motion setting method for a transfer press including a press machine configured to move a slide up and down in accordance with pressing motion, and a transport device configured to move a retainer in accordance with transfer motion to transport a workpiece, the motion setting method comprising the steps of:

• creating, based on the pressing motion provisionally set and the transfer motion provisionally set, an operating curved surface which has been made three-dimensional based on a relative distance of the retainer relative to a standard upper die attached to the slide;
• determining, by comparing a standard upper die interference curved surface with the operating curved surface that are placed in a same three-dimensional coordinate system, whether the operating curved surface is present within an interference region of the standard upper die interference curved surface, the standard upper die interference curved surface having been obtained by making a standard upper die interference curve three-dimensional;
• and
• when the operating curved surface is determined to be present within the interference region in the determining step, changing a relative phase of the transfer motion relative to the pressing motion,
• after the changing step, the determining step being performed again by comparing the standard upper die interference curved surface with the operating curved surface having the relative phase changed.
