本文探討磨削加工過程中之加工特性，包括砂輪之填塞及磨耗、比磨削係數以及磨削穩定性。在填塞及磨耗方面，以實驗的方式觀察磨削道次之影響；在穩定性方面，首先探討捲積磨削力模式及磨削系統穩定性的機制，接下來利用磨削系統中工件磨耗、機台剛性、砂輪接觸及磨耗剛性分析的結果，建立磨削穩定性與製程剛性之間的關係，並透過捲積磨削力模式判認實驗過程中之工件磨耗剛性，以分析其對磨削穩定性之影響。最後利用此分析流程及磨削實驗之結果，探討不同工件及加工條件對磨削穩定性之影響。
由實驗及分析的結果發現由於砂輪填塞以及磨粒鈍化，使得磨削力隨著研磨道次穩定地增加；砂輪的磨耗量也會隨工件之比磨削能增加而上昇。在穩定性方面，本文比較三種材質之硬化鋼料，分別是中鋼工輥鋼材，SKH51高速鋼及SKD11模具鋼。在加工條件方面，磨削深度對工件磨削剛性的影響較小；而隨著工件進給速度增加，其工件磨耗剛性也隨之上升。

This thesis investigates the grinding characteristics, including the wheel loading and wears during a grinding process, grinding coefficients and stability of different hardened steels and grinding parameters. The observation of wheel loading and wear are achieved by grinding experiments, and the relationships between the grinding force and ground length on the workpiece can be obtained. In the analysis of grinding stability, the convolution grinding force model and four mechanism of grinding system, including wheel contacting stiffness, machine stiffness and wheel and workpiece wear stiffness, are investigated. The process stiffness can be identified by the analytical nature of convolution grinding force model, and the stability of the grinding process can be evaluated by the identified process stiffness. By this analyzing procedure, the effects of different workpiece material and grinding parameters to the grinding stability can be analyzed and discussed.
The experiments showed that the grinding force increased steadily with the grinding length, because the blunt grits and wheel loading were produced during the grinding process. They also showed that the wheel wear would be more increased by higher specific grinding energy. In the stability analysis, this article compared different hardened steels, including roller steel provided by China steel corporation, SKH51 and SKD11, and found that among them. It was also found that the grinding depth does not have a significant effect on stability but higher workpiece feed resulted in higher workpiece wear stiffness.
