Abstract:
A bending order determining method for a bending machine comprising the steps of:obtaining a correction value for a die driving amount with respect to a reference bend based on measurements of the bend angle of the reference bend;calculating a correction value for a die driving amount with respect to an objective bend from the correction value for the reference bend, in producing a plurality of bends in a workpiece;selecting a suitable bending order from a plurality of bending orders possible for bending operation, based on evaluation of bending accuracies of objective bends to be formed in each bending order, the evaluation being carried out with a specified measure,wherein said evaluation with a specified measure comprising the steps ofassigning a weight to the bending accuracy of each of objective bends formed in each bending order, based on the degree of the correlation between the processing factors of the objective bend and the processing factors of its associated reference bend, and thensumming the weights assigned to all the objective bends with respect to each bending order to obtain an evaluation value for each bending order.
