METHOD FOR PRODUCING SQUARE UNITS

WIPO Patent Application WO/2010/104330

A2

The present invention relates to a method for producing square units, which involves cutting out, from a relatively larger square base material, two or more types of square units with a relatively smaller size than the former, using a cutting frame with cutters. The method comprises: (a) an inspection step of scanning the square base material in the lengthwise direction and the widthwise direction of the square base material to check the position of defects on the square base material; (b) a step of calculating yield rates for each of two or more types of cutting frames by means of a virtual cutting of the square base material; (c) selecting, on the basis of the value calculated in step (b), one cutting frame from among the cutting frames with a yield rate that falls within the top 30%; and (d) cutting the square base material using the cutting frame selected in step (c) to produce square units.
