摘要

過去在鑽削加工上著重於鑽削不同材質如何選擇適當的鑽削參數；而在鑽頭研磨方面也多半考量鑽頂幾何及其與鑽削力學間的關係。對於研磨輪的選用、研磨輪的修整、修磨次數及研磨液的使用等不同的鑽頭研磨參數選擇，以及鑽頭的鑽削性能及鑽孔品質的影響，則較少提及。
本研究以鑽頭研磨參數為研究對象，應用田口實驗計劃法規劃鑽頭研磨實驗，以刀具研磨機加裝鑽頭附件研磨鑽頭，並使用綜合加工機進行低碳鋼材質工件的鑽削。以田口方法規劃實驗，雖減少實驗次數但仍由田口實驗計劃法中所設定的實驗配置中取得數據，作為分析的依據，藉由SN比輔助表取得鑽頭研磨參數的最適條件。並透過變異數分析的方式，得到鑽削性能實驗、鑽孔品質實驗中各因素對結果產生的影響程度。最後則以最適條件因素進行確認試驗，與工程推定值相較，重現性為3.61％～24.5％的範圍內。

In the past, the key point of drill fabrication was focused on how to select proper parameters to apply to different materials. In addition, the most of the time we considered the drilling geometry and the relation between Drilling Geometry and Drilling Force. But people less mentioned about the drill grinding parameters for the selection of grinding wheel, modification of grinding wheel, times of grinding and usage of grinding liquid which would influence the drilling capacity and drilling quality.
This research was subject to the parameters of drill grinding to apply Taguchi Method to plan the drill-grinding test. To use the tooling grinding machine equipped with drill enclosed with grinding drill, also to use multifunction tooling machine to process (drill) the low carbon object, and analyze the different parameters of drill grinding influence the drilling capacity and drilling quality. Although we reduced the testing times and still can get the result data to do analyzing from the testing arrangement fixed according by Taguchi Method and referring the SN Ratio Assistant table to obtain the most proper parameters of driller. Furthermore, to know how they affect to the result from various testing factors of the drilling ability experiment and drilling quality experiment by means of the Analysis of Variance. The last, we used the most proper conditions and factors to do reconfirming test. To compare with the forecast value of this project, the repeat was still in the 3.61％～24.5％ range.
