摘要

本研究利用田口實驗法最佳化薄化的平面顯示器玻璃切割製程，透過品管手法，魚骨圖與因果關係圖找出五個重要的因子，包括切割刀輪角度、切割刀輪齒數、切割刀輪齒深、切割速度與切割壓力，以1個2水準因子與4個3水準因子進行L18(21X37)直交表實驗，反應變數為玻璃切斷面裂片深度。經過訊號雜音比的轉換，探討每個因子的影響程度與每個因子水準變化量對於反應變數的影響程度，找出最佳化的玻璃切割用刀輪選擇與切割製程條件。本論文實地測試結果，顯示改善後降低了不良率0.115%的發生。

This study aims to optimize the cutting process of thinning TFT-LCD display glass with the Taguchi method. I find the top 5 experiment factors by fishbone diagram and C&E matrix, including cutting wheel angle，cutting wheel teeth，cutting wheel depth，scribe speed，scribe load. This thesis executes the experiment by L18(21X37) orthogonal arrays including one 2-level factor and four 3-level factor. The response variable is designated as the cutting vertical depth of glass cross sections. Response variables are transformed into signal - to - noise ratios to investigate the relationship between effects of every factor and the change of factor levels. Finally,optimized cutting wheel types and cutting process recipes are determined. The test result of this thesis shows the defect rate is thus reduced by 0.115%.
