Title:
BENDING ORDER SELECTING METHOD IN BENDING MACHINE AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/1997/030803
Kind Code:
A1
Abstract:
A bending order is selected so as to make a bending accuracy best. A bending order electing method comprises generating a plurality of bending orders, which enable bending, in a bending order generating unit, judging in a measuring possibility judging unit whether measurement of a bending angle in order of respective bending steps for respective bending orders generated is possible, setting in a correction condition setting unit bending corners, on which calculation of correction values for a sizing amount of a die associated with a bending corner, which is judged impossible to measure, is based, setting weighting of a degree of correlation between a working factor for the bending corner, which a weighting setting unit judges impossible to measure, and a working factor for those bending corners, which are set by the correction condition setting unit, calculating a sum of weighting values for all the steps in a weighting calculating unit, and evaluating the calculated sum of weighting values in the bending order selecting unit to select an appropriate bending order from the respective bending orders to output the same to an NC apparatus.
