碩士 === 逢甲大學 === 材料與製造工程所 === 96 === According to the increasing demand for high precision in modern machining applications, the surface roughness that is one of the most important performance indices has continuously been investigated. In a typical milling operation, due to the cutter geometry and cutting process, the cutting remainders or marks are left on the part surface, and consequently the surface roughness is formed. In this thesis, we focus on the theoretical analysis and experimental verification on the surface roughness in end-milling process. In the thesis, we first develop the roughness model based on the motion trajectories of the cutter edges. To verify the theoretical model, we conduct a series of end-milling process with different cutters (��10 HHS and ��16 Ti-coated HSS), parts (Al-6061 aluminum alloy and S25C carbon steel), and cutting conditions.
