During the cutting process, when a defect is positioned in a cut glass piece, it is, most of the time, rejected as a quality loss. In this case, it is necessary to recut a glass piece of the same size from the jumbo. This reduces significantly the productivity of the line. To avoid this loss, one option is to adapt the cutting plan to the defect map measured at the exit of the float process and position the defects inside the "natural" geometrical glass losses of the cutting plan instead. This talk will detail the associated industrial ecosystem of glass manufacturing and cutting and how such re-optimization is performed. We will also discuss the importance of having a digital twin of the existing system and how it can be used to drive value.
