<p>Working factors which influence a bending angle are specified from data sent from an NC device (10) in a grouping factor specifying section (13), and a tolerance at the time of grouping is set for the specified factors in a tolerance setting section (14), whereby grouping of corners to be bent is performed in a corner grouping section (15). Compensating conditions are then set in a compensating condition setting section (16), and compensating data for a depth amount is calculated based on actual depth data of a corner bending performed on a good product in a compensating data calculating section (17) based on the compensating conditions so set, and process data of the bending process is changed in a process data changing section (18). Thus, the depth amount of a corner to be bent is compensated whose bending angle measurement is not performed based on a compensating value for a depth amount of a specific corner to be bent for which a bending angle has actually been measured.</p> |
