當今科技日新月異，各式電子產品推陳出新之速度更是迅速。作為智慧型電子產品中最主要之螢幕生產，以單晶鑽石刀刨削導光板模棱結構之加工方式，也在精度要求與縮短加工時間上日益嚴苛，使傳統上依靠加工師傅經驗判斷，或是必須將工件與刀具卸離機台方能檢測之方法不敷使用。因此本研究延續曾慧君等人所提出之雷射散射檢測法[1]，探討切削液對該檢測法之影響，以使該檢測法朝線上檢測更進一步。依據研究結果，可知道若欲檢測有切削液之工件，須使雷射光以接近垂直工件表面之方向入射，且切削液使用量不得過多，以利切削液達到靜態穩定。在適當架設與接收散射光訊號後，可以得到散射光強度將隨刀鼻半徑增加而上升，可用於間接監測刀鼻半徑以掌控換刀時機與工件品質，有利於節省成本與效率之提升。

While manufacturing the light guide plate, single crystal diamond tool is often selected to produce surface structure on the die core. Since the surface profile is determined by the tool’s shape, the tool wear become a crucial problem. However, we still rely on machinist’s experience to judge the tool is useable or not. This paper provides a further research for the optical scattering monitoring method proposed by Hui-Chun Tseng et al. As the results of the experiment show, while monitoring workpiece with cutting fluid, the incident angle of laser should be as small as possible. Also, the amount of cutting fluid should be as little as possible. Last, whether there is cutting fluid or not, the power of scattering light increase as the tool’s nose radius increase, which means the monitoring method works.
