| Abstract |
With increasing in size of glass substrates for flat panel, both high productivity and high
quality are required for its edge rounding process. In order to understand the effect of process speed
on the strength of glass substrate, this study performs a profile grinding at the substrate edge with
varied feed rate. The obtained glass substrate then undergoes a four-point bending to evaluate its
strength. Weibull distribution is used to analyze the fracture strength of glass substrate after
edge-rounding process and to correlate the removal rate with the quality of the process. |
