碩士 === 中原大學 === 機械工程研究所 === 92 === 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.
