摘要： A bending order which provides a highest possible bending accuracy is determined.
First, a bending order generating section generates a plurality of bending orders possible for bending operation. Then, whether the bend angle of each bend can be measured in each generated bending order is checked by a measurement judging section. For each bend which has been determined as an objective bend "impossible to measure", a reference bend whose correction value for a die driving amount is to be used for calculating a correction value for the objective bend is set by a correction condition setting section. Weighting is carried out by a weight setting section 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 the weights assigned to all the objective bends are summed by a weight sum computing section. Thereafter, a bending order selecting section evaluates the respective weight sums of the bending orders to select a suitable bending order and outputs the evaluation result to an NC device.

摘要： A bend angle correction method directed to carrying out simple and accurate penetration of a movable die into a fixed die to produce a uniform angle throughout the length of a workpiece, being unaffected by material variations. When bending a sheet-like workpiece to a desired angle by the cooperative movement of a movable die (punch) driven by three or more drive shafts and a fixed die (die) disposed in an opposing relationship with the movable die, the bend angle of the workpiece is measured during bending operation and the difference between the measured bend angle and a target angle is obtained, at at least three points which are the ends and center of the workpiece. Based on the differences, correction amounts for the penetration of the movable die are obtained on a shaft-load imposed point basis.
