本研究運用機械切割方式對玻璃進行切割，在玻璃表面直接切下，產生大約為玻璃厚度10~20%的裂縫深度，再由機械應力的方式將玻璃扳裂，搭配ANSYS以有限元素法(FEM, Finite Element Method)，進行相關研究及比對，評估其未來切割條件的改變使得生產良率的提升之可行性。
本文研究目的主要為利用有限元素法找出切割後表面破片應力分佈狀態，並以實體基板切割後產生水平裂痕(Median crack)之結果，與切割參數調整刀壓及壓入深度之討論，比對有限元素分析後結果，作為切割後外觀品質好壞之探討，減少可能增加之外觀不良之風險。

This study is the method of using the mechanical type to cut the substrate of the glass , under the circumstances that the glass surface is cut directly, probably produced 10∼20% of the depth of crack that is the thickness of glass, and then pulled the glass and split by mechanical stress , use the ANSYS and finite element method carry on relevant research and compare, survey the perfect cutting parameter to increase the yield in the future.
This study is in order to find out the surface fracture stress distribution status after cutting and take advantage with the finite element method ,and compare with the result of median crack when glass substrate after cutting .It discuss with change parameter of the cutting pressure and Cutting depth ,than to compare with finite element method, it regard as discussing the quality after cutting to reduce the risk of surface defect.
