摘要
通过显微压痕和纳米压痕试验,研究了Soda-lime光学玻璃在微/纳米尺度下的材料去除机理,发现外加载荷的幅值对脆性材料变形方式有直接影响。对光学玻璃的金刚石普通切削和超声振动切削试验结果表明,超声振动切削的实际有效切削深度与名义切削深度有着较好的一致性,合理选择金刚石超声振动切削参数可实现光学玻璃的塑性域切削。
The material removal mechanism in micro-cutting of soda-lime optical glass was analyzod by micro and nano indentations. The magnitudes of applied loads were found to exert a considerable influence on material deformation mode. Conventional and ultrasonic vibration assisted diamond cutting tests of soda-lime glass were performed. Real depths of cut in ultrasonic vibration cutting correspond well with the nominal ones. Ductile regime cutting of the optical glass can be realized by selecting process parameters properly.
