PROBLEM TO BE SOLVED: To precisely and efficiently manufacture a die capable of setting the dimension of a molded piece within a prescribed allowable error range in a process of glass mold press molding. SOLUTION: This system is provided with a die working machine 1 for working a die according to an NC program, a die measuring device 11 for measuring a die 5a worked by this die working machine 1, a mold press molding machine 31 for molding a molded piece 6 by using the die 5a, a molded piece measuring device 41 for measuring the dimension precision of the molded piece 6 molded by the mold press molding machine 31, a computer 64 for centralized control, and a computer 54 for NC program preparation for preparing an NC program. When the measured data of the molded piece 6 measured by the molded piece measuring device 41 are beyond the allowable error range based on the measurement reference value of the molded piece 6, the computer 64 for centralized control prepares data for correction for correcting the NC program from a value obtained by comparing the measured data of the molded piece 6 with the measurement reference value of the molded piece 6 and a value obtained by comparing the measured data of the molded piece 6 with the measured data of the die 5a, and the computer 54 for NC program preparation corrects the NC program.
