Abstract:	在研磨相關硬脆材質的材料時，其研磨的加工過程中，穩定性的部分在工件夾持的系統(砂輪、調整輪、刀板間的調整加工狀態)中是較易受影響的。而無心研磨只有在設置參數為最佳時才能生產出高生產力、高精密的產品。本文介紹了研磨系統就穩定性的幾個標準條件並提出了指導方針，如何正確選擇研磨加工設置之條件，以避免共振、打滑、顫紋及圓筒度相關的問題。最後，運用演算的方式提供最佳的參數設置條件來增加其製程穩定性及加工效率，除了可以透過製程加工研發之參數及條件外並可以增加其效率並降低其成本，基於製程之目標提出模擬之結果並進行相關的應用潛力。 ;Centerless grinding process is widely used in producing the extra-smooth surface, particularly in the hard and brittle materials such as aluminum oxide (Al2O3), zirconium oxide (Zr2O3) and silicon carbide (SiC). The stability of the centerless grinding process is very sensitive to the set-up conditions due to the uniqueness of the work-holding system. Centerless grinding produces precision components with high productivity only when the set-up condition is optimally chosen .This thesis describes the effect of set-up conditions on the stability criteria of the centerless grinding system . Guidelines are proposed for determining proper set-up conditions to avoid spinners, chatter vibration and roundness problems. Finally, the optimum set-up condition based on experiments are proposed and the validation results are discussed.
