Title:
METHOD AND DEVICE FOR CORRECTING GO SIZE FOR WORKING OF WORK WITH SHEET METAL WORKING MACHINE
Document Type and Number:
Japanese Patent JP3212014
Kind Code:
B2
Abstract:
PURPOSE: To rapidly and exactly obtain the set sizes of correct back gages by subjecting a sheet metal work to trial working at the time of initial setting of the back gages, measuring the sizes, inputting the actually measured sizes to an NC unit and determining correction rates.
CONSTITUTION: The back gages 1 are first set in the normal initial positions and the trial bending, etc., of the work W are executed in sheet metal working. The height sizes(a), (b) of the two pieces of the right and left flanges 5 of the work product are measured as a result thereof and whether the sizes are correct to the prescribed values or not is checked. The actual working operation is started if the results are correct. The actually measured sizes are inputted to the NC unit if the results are not correct. The control section of the NC unit executes calculation in accordance with a set program and emits driving commands to respective ball screw mechanisms to automatically correct the go sizes of the right and left back gages 1, 1. The trial bending is executed again in the corrected back gage positions and the sizes thereof are measured. The actual production working operation is started if the results are correct.
