摘要/Abstract

摘要：

应用VW-6000/5000动态三维显微系统对游离磨料线锯切割过程中磨粒的运动状态进行分析,结果表明磨粒在切割区域存在两种状态:一种为接触状态，另一种为非接触状态。同时应用0.16mm表面涂有树脂的线锯和普通线锯对光学玻璃K9进行切割实验,验证了游离磨料线锯切割去除机理。实验结果显示,普通线锯的切割效率大大高于涂有树脂的线锯的切割效率，切割工件表面均为微细凹坑，没有划痕，而且切割后涂有树脂的线锯表面嵌有许多磨粒，普通线锯表面有许多微细凹坑，均表明游离磨料线锯切割机理主要以“滚压”去除为主。

Abstract:

VW-6000/5000 dynamic microscope system was used to observe the motion state of the abrasive particles in the free abrasive wire sawing.The results show that the abrasive particles have two states in the cutting area,one is contact state,another is non-contact state.Optical glass(K9) was cut by 0.16mm wire saw coated with resin and steel wire saw and sawing mechanism has been proved.The results show that slicing efficiency of the steel wire saw is much higher than that of wire saw coated with resin.Surface of the as-sawn optical glass by steel wire saw has many tiny pits but no scratch.Surface of the as-sawn wire saw coated with resin has many abrasive particles and surface of steel wire saw has many tiny pits.These results indicate that sawing mechanism is mainly rolling-indenting removal in the free abrasive wire sawing.

Key words: wire saw, free abrasive machining, abrasive particle motion, sawing mechanism
