摘要

本文通过在锯切用超薄切割砂轮的径向上辅加超声振动的方法，对两种不同物理特性的光学玻璃进行锯切加工实验，探索了径向超声振动对光学玻璃锯切过程的影响。理论分析了超声振动锯切过程中的锯切力和锯切比能，给出了单颗磨粒在普通锯切与超声振动锯切时的切削路径。采用有无超声振动辅助锯切两种方式对K9玻璃和石英玻璃进行锯切实验，分析了超声振动对光学玻璃锯切力和锯切比能的影响。结果表明，相比于普通锯切方式，除了受到加工参数的影响外，超声振动辅助加工时K9玻璃和石英玻璃的锯切力减少幅度分别在30%～50%和50%～65%，锯切比能分别减少了30%～45%和50%～60%。径向超声振动辅助锯切使材料产生微破碎，具有减小锯切力和比能的作用，因此有利于提高光学玻璃材料锯切效率和改善加工质量。

Abstract

Based on ultrasonic vibration added in radial direction of saw-cutting ultra-thin abrasive cutting wheel

two kind of optical glasses with different physical properties were fabricated to explore the influence of radial ultrasonic vibration on saw-cutting process. The sawing force and sawing energy were deduced theoretically

and the cutting paths of single abrasive in conventional and ultrasonic assisted sawings were represented. Then K9 glass and quartz glass were machined by ultrasonic assisted sawing

during the process the effects of ultrasonic vibration on sawing force and sawing energy were tested. Experimental results show that

compared with common sawing method

apart from influence of processing parameters

ultrasonic vibration can reduce the sawing forces in the processes of K9 and quartz by 30%-50% and 50%-65% respectively

and the specific energies accordingly by 30%-45% and 50%-60%. Radial ultrasonic vibration-assisted sawing breaks the material slightly and reduces the sawing force and sawing energy

therefore can promote sawing efficiency of optical glass materials and improve processing quality.
