Computational Methods for Determining the Effect of Stress on Cutting Quality1

The characteristics of the residual stresses arising in float-glass production are presented. The forms, causes, magnitude and direction of the stresses are described. The condition for off-cut breakage is derived mathematically. Modeling with ANSYS Structural Ver. 14.0 is used to obtain the stress pattern when the breaking bar is raised and the critical parameters for which glass losses occur during cutting are determined.
