Title:
AUTOMATIC CORRECTING METHOD FOR DIE DEPTH AMOUNT
Document Type and Number:
Japanese Patent JP3666925
Kind Code:
B2
Abstract:
PURPOSE: To improve the precision of a bending angle and to shorten the working time even if a work has a bending corner of being hardly measured or unable to be measured.
CONSTITUTION: The working factor influencing the bending angle is specified by the data from an NC device 10 in a grouping factor specifying part 13, the allowable range at the time of grouping is set against this specified factor in an allowable range setting part 14 and grouping of bending corners is executed in a corner grouping part 15. Then, the correcting condition is set in a correcting condition setting part 16, based on this set correcting condition, the correcting data of the depth is calculated based on the real depth data of the bending corner worked to an article of good quality in a correcting data calculating part 17 and the process data of bending is changed in a process data changing part 18. In such a way, the depth of the bending corner whose bending angle is not measured is corrected based on the correcting value of depth regarding to the specified bending corner whose bending angle is measured.
