METHOD FOR DETERMINING THICKNESS OF GLASS RAW MATERIAL FOR PRECISION PRESS MOLDING, METHOD FOR MANUFACTURING GLASS RAW MATERIAL FOR PRECISION PRESS MOLDING, AND METHOD FOR MANUFACTURING GLASS OPTICAL ELEMENT
METHOD FOR DETERMINING THICKNESS OF GLASS RAW MATERIAL FOR PRECISION PRESS MOLDING, METHOD FOR MANUFACTURING GLASS RAW MATERIAL FOR PRECISION PRESS MOLDING, AND METHOD FOR MANUFACTURING GLASS OPTICAL ELEMENT
The present invention relates to a method for determining the thickness of the glass material for precision press molding. Made of the same glass material as the glass molded article to be obtained by the precision press-molded with the same volume, and the glass molded article than the test press for press-forming such that the thickness of the glass molded article to the glass material for the thick test, obtain will perform the forming, by the thickness deformation and strain rate and the other press load of correlation to fill out the approximate line representing the at least two types of embodiments according to the test press molding, create at least two types of the approximate line and the value of the deformation amount of the thickness in the intersection of the approximate line was created, to obtain more than a numeric value obtained by adding the thickness of the glass molded body, and determines the thickness of the glass material for precision press molding. ;
