陶瓷材料目前廣泛的使用於半導體之基板材料、機械零件、光電元件上,但由於硬脆陶瓷材料極難機械加工,加上硬脆陶瓷材料的需求也逐年增加,在過去中使用游離磨料加工硬脆材料,其效率過低與磨料浪費性過高,為了更有有效率的達到工業上所需求的高精度及較佳的表面品質,因此本論文透過固定鑽石線鋸鋸切硬脆陶瓷材料(氧化鋁與碳化矽),分析其線鋸鋸切特性及量測表面粗操度,並使用掃描式電子顯微鏡觀察硬脆陶瓷材料的切屑生成型態,藉由切屑型態研究脆性破壞模式與延性加工模式下的材料移除機制,最後藉由控制參數以達到硬脆陶瓷材料之延性加工而使得加工效率較高與表面粗操度較佳之外,同時亦可以使得加工變質層較薄,以提高加工上品質的需求。
At present, ceramic materials are extensively used in substrate materials of semiconductor, mechanical and photoelectric devices. Not only brittle materials are very hard to machining, but also the requirement increase with time. Free abrasive machining for brittle materials had been used in the past, however its efficiency was so low and waste a lot of slurry. In order to gain high accuracy and fine surfaces quality in industrial requirement more efficiently, so this paper uses Fixed Diamond Wire Saw to slice Silicon Carbon and Alumina. To analyze saw slicing properties and measure surface roughness, we use SEM to measure chip formation of ceramic materials. These methods can help us to know the brittle fracture mode and ductile regime grinding mode in ceramic materials remove modes. Finally, we condition parameters to gain ductile regime grinding mode of slicing ceramic materials. These methods can slice more efficiently and improve surface roughness more excellently. Ductile regime produces thin deteriorate layer and increases requirement of industry.
