鑽頭歷史發展久遠，種類眾多，用途廣泛，一直到現在還是切銷加工最常使用的工具之一。影響鑽削性能的因素很多，如鑽頭材質、鑽床、工件材料、加工條件、切削液以及鑽頭幾何形狀等。

　　本研究將就鑽頂的幾何設計進行改良，而本研究所探討的鑽頭較傳統鑽頭多了幾個刀面，因此命名為多面鑽。而多面鑽的幾何設計相較傳統鑽頭來的複雜許多，文中將會對多面鑽頭的各部位幾何設計方式及參數設定來進行分析。
　　
　　為了實際加工出多面鑽頭，文中也會對CNC６軸工具機建模，建立研磨出多面鑽頭的加工方法，文末會以手動加工之方法以文中設定之參數製作出多面鑽。

Drills hasa longhistorical development, many species ofwide range of uses, until now, it’s the most commonly usedtools. There’s many factorssuchasdrillmaterial, machining conditions, cutting fluidsanddrillgeometryand so onin drillingperformance .

　　In this study, we will improve the design of drills geometric,this drillhas a few morefacet thanthetraditionaldrill ,so namedfor themulti-faceteddrill. Thegeometric design ofthemulti-faceteddrillis more complex tothetraditionaldrill ,the textwillbein all partsofthemulti-faceteddrillgeometric designmethods andparameter settingsfor analysis.

　　Forprocessing ofthemulti-faceteddrill,we will modeling the CNC 6 axis machine tool to establishment themethods of grinding multi-facet drill, in the end we use manual processing methodsto producemulti-faceteddills.
