摘要：
An effect of cutting fluids on fracture stress of soda-lime glass is discussed. In water the stress is greatly decreased and many uncontrollable cracks are easily generated and propagate. In order to obtain a defect free surface in machining of glass, the generation and propagation should be controlled or restrained. Since the generation is greatly affected by a surface energy or a fracture toughness of surface region, some increasing methods of the toughness are proposed. Proposed methods can increase the toughness.
