Abstract
Official abstract text for this publication.
A method of cutting one or more kinds of quadrangular unit pieces having a relatively small size from a quadrangular base material having a relatively large size uses a cutter frame including a plurality of cutters to manufacture the quadrangular unit pieces. The method includes (a) scanning a quadrangular base material in a longitudinal direction and in a lateral direction to check positions of defects on the quadrangular base material, (b) calculating a yield when cutting the quadrangular base material using two or more kinds of cutting frames, (c) selecting one of the cutting frames in which the yield calculated at the calculation step (b) is within a range of upper 30%, and (d) cutting the quadrangular base material using the cutting frame selected at the selection step (c) to manufacture quadrangular unit pieces.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of cutting one or more kinds of quadrangular unit pieces having a relatively small size from a quadrangular base material to manufacture the quadrangular unit pieces, the method comprising: (a) an inspection step of scanning a quadrangular base material in a longitudinal direction and in a lateral direction of the quadrangular base material to check positions of defects on the quadrangular base material; (b) a calculation step of calculating a yie…
