摘要: 現今微銑刀的製造方法有研磨加工、LIGA製程、雷射加工、離子束加工、放電加工等方式,其中放電加工更是具有高加工精度、耗費成本低之優點。而在本文使用五軸線放電加工機製造微銑刀,由於線切割機之電極線是連續移動的,故沒有電極消耗的問題,在製造微銑刀時擁有相當高的精度。 本文使用ANSYS來確定單刃微銑刀之最佳幾何外形在藉由田口實驗法來探討實驗放電參數與表面粗糙度值的關係,由放電參數最佳化可得到最佳表面粗糙度值Ra=0.538μm。在討論不同主軸轉速和放電尺寸與表面的關係,在主軸轉速為500rpm下可得最佳尺寸和表面品質。由實驗所得之結果,製造出目標尺寸ψ200μm之微銑刀,並成功加工鋁合金6061。
To make a micro-milling can be used with grinding machining, LIGA process, laser processing, ion beam processing, E.D.M., etc. The EDM provides high machining accuracy, lower cost advantages. In this research, using the 5-axis EDM machine to make a micro-milling, due to the electrode wire cutting line is a continuous movement, it is no consumption of electrode, it provide high accuracy. Our research use ANSYS to determine the best single-edge micro-geometry cutter, to use Taguchi method explore the experimental discharge parameters and the relationship between surface roughness values from the discharge parameters, and get the best optimizing parameter of the surface roughness Ra=0.538μm. To discuss the different spindle speed and discharge the relationship between size and surface, under the spindle speed of 500 rpm can get a best available size and surface quality. The results obtained from the experiment, to create a target size ψ200mm of the micro-cutter, and successfully processed aluminum alloy 6061.
