This disclosure is directed to techniques for utilizing various sensors and models to evaluate glass as it progresses through the tempering process in order to ensure that the tempered glass is of a proper quality. If, according to any of the various sensor measurements, the tempered glass is not of a proper quality, the system may automatically adjust one or more settings in any of the various components of the system in order to bring future panes of tempered glass back to having the proper quality. The system can measure for any number of glass characteristics or system characteristics, including edge quality, vertical flatness, haze, washing process variables, thermal imaging, distortion, blower information, production data, and furnace process data.

The computer-implemented method for glass bending includes obtaining a deviation of a real shape of a glass from a desired shape of the glass, the glass is produced by a glass bending process; determining a variation of at least one parameter associated with the glass bending process, at least in part based on the deviation of the real shape from the desired shape; and adjusting the at least one parameter based on the variation for compensation of the deviation.
