科技無時無刻都在進步的現在，產品的尺寸精度及公差要求越來越精準，加工技術上必須有新的突破，故對於材料的特性與適當的加工方式等都必須列入考量。工欲善其事必先利其器，凡是加工生產上都必須有適當的工具才能事半功倍。以切削加工為例，切削刀具的設計需針對材料性質及需求目標做考量，才能達到目的同時也可以減少刀具在加工時所產生的磨耗現象。
本論文主要研究端銑刀的幾何角度公差對於工件表面粗糙度及刀腹磨耗的影響，目前業界對於端銑刀的角度公差都採用±1°，故探討徑向切削角及徑向離隙角在公差±1°~ ±3°時，工件的表面粗糙度與刀腹磨耗的變化。公差的容許大小會影響到生產成本，所以本文除了探討加工的影響外，也考量到設定公差的選用，若在不影響工件的加工品質條件下，對於角度的量測就可以選用較大的公差，如此可以降低不良品的刀具，使得整體的成本降低。

Now that science and technology are improving all the time, the dimensional accuracy and tolerance requirements of products are becoming more and more precise. There must be new breakthroughs in processing technology. Therefore, the characteristics of materials and appropriate processing methods must be considered. Workers must first sharpen their tools if they want to do their best, and all processing and production must have appropriate tools to do more with less. Taking the cutting process as an example here, the design of the cutting tool needs to be considered in terms of material properties and demand goals, in order to achieve the purpose and reduce the wear phenomenon of the tool during processing at the same time.
The main research of this thesis is the effect of geometric angular tolerance of end mill towards the surface roughness of workpieces and flank wear. At present, the industry uses tolerance of ± 1°, and this article discusses the change of surface roughness of the workpieces and flank wear while the tolerance of radial rake angle and radial relief angle lie within ± 1° ~ ± 3°. The size of allowable tolerance will affect the production costs. Apart from discussing the impact on the processing, the application of the setting tolerance is considered. If it does not affect the processing quality, one can choose a large tolerance value for processing to reduce the defective products and overall cost.
