Abstract
The present invention is devised to solve the problems of the above-described conventional technologies. The purpose of the present invention is to provide a tempered glass cutting method and cutting apparatus which can prevent the defects of the tempered glass breaking when same is cut and improve the reliability of the product. To this end, provided is a tempered glass cutting method which comprises: a tempering step of generating compressive stress on a glass sheet to temper the glass sheet; a compressive stress relaxation step of applying heat to the cut portion of the tempered glass sheet to relax the compressive stress; and a cutting step of cutting the cut portion.
