本研究內容主要分為三個部分，首先，延續之前所開發之微型無屑螺絲攻AOI量測系統，以相同的硬體架構為基礎，持續開發軟體模組之節距與倒角角度量測功能，提升微型無屑螺絲攻AOI量測系統之完整性與檢測效率。其次，透過3D建模軟體Creo3.0之Pro/MECHANICA進行微型無屑螺絲攻特徵之優化設計，著手於微型無屑螺絲攻之倒角角度與鏟磨量進行特徵優化之分析，透過改善原始幾何之設計來降低攻牙時絲攻所受應力，提高微型無屑螺絲攻使用壽命，以期降低業界生產之成本。最後，以攻牙孔數探討微型無屑螺絲攻之刀具壽命，根據飽牙率與受力之大小找尋最佳下孔徑，後續以微型無屑螺絲攻攻牙於厚度1mm之不銹鋼SUS304板材，量測微型無屑螺絲攻的磨耗狀況，探討與分析攻牙孔數與磨耗量曲線圖，包含磨耗長度指標-攻牙孔數曲線圖、磨耗寬度指標-攻牙孔數曲線圖、徑向磨耗-攻牙孔數曲線圖、軸向推力-攻牙孔數曲線圖、扭矩負載-攻牙孔數曲線圖，期盼研究結果可提供業界作為攻牙製程之參考。

This research mainly focuses on three parts, namely, the improvement of the former developed automatic optical inspection (AOI) system of the micro fluteless taps, the design optimization of the geometric features of the fluteless taps, and the tool life investigation of the tapping for SUS304 stainless steel sheet. Regarding the improvement of the developed AOI system, the software modules for the efficient inspection of the pitch and the chamfer angle have been amended based on the same hardware architecture. Concerning the reduction of the manufacturing cost and the increase the tool life of the micro fluteless taps, the optimal design of the geometrical features of the micro fluteless taps has been carried out. This study focuses on two parameters design of the taps by Creo3.0 Pro/MECHANICA software, including the chamfer angle and the shovel depth, respectively. With regard to the tool life investigation of the tapping, this study aims to analyze the tool life of the micro fluteless taps in terms of the number of tapping holes and to find the optimal diameter of the leading hole. According to the experimental results for tapping the SUS304 stainless steel plate with the thickness of 1mm, the tool wear results have been determined. The plot of the number of holes versus tool wears including wear length vs. tapping number, wear width vs. tapping number, radial wear vs. tapping number, thrust force vs. tapping number, and torque vs. tapping number, have been obtained in this study. The research results regarding micro fluteless tapping are expected to be used as a helpful reference for the industry.
