Summary:Damage‐free chamfering method for strengthening a glass edge was introduced and its effect on the edge property was discussed in detail. The chamfered surface was evaluated using an optical microscope, a confocal LSM, and a birefringence measurement system. The mechanical properties were characterized by measuring hardness, Young's modulus, and bending strength. The results revealed that the cut edge of 0.55t thin glass sheet containing median cracks and chips was exfoliated uniformly to a thickness of 200 μm, and a smooth edge surface was created (Ra = 0.03 μm). We also reported that the chamfered surface had a compressive stress enabling hardness and Young's modulus increase, and the edge strength improved from 117 to 199 MPa.
