Abstract:
1. 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 using a cutter frame comprising a plurality of cutters to manufacture the quadrangular unit pieces, the method comprising: 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; a first calculation step of calculating a first yield when imaginarily cutting the quadrangular base material using two or more kinds of virtual cutting frames set at a first position that includes the defects; a selection step of selecting one of the virtual cutting frames; a second calculation step of calculating a second yield at a second position by moving the selected virtual cutting frame in the lateral or longitudinal direction from the first position to the second position, wherein the virtual cutting frame is set in the lateral or longitudinal direction from the first position to the second position when an increase in yield is 20% or more; a manufacturing step of cutting the quadrangular base material using a cutting frame corresponding to the virtual cutting frame selected at the selection step and set at the first or second position having the highest efficiency to manufacture quadrangular unit pieces.
