摘要

本文應用田口法探討直徑0.4mm微鑽頭於鑽削Inconel 718所產生最小磨耗之最佳鑽削參數。利用三眼實體顯微鏡和電腦影像擷取及分析系統，進行微鑽頭鑽刃刀腹磨耗影像處理及量測，以計算微鑽頭經鑽削過後鑽刃的磨耗面積。本文田口法規劃四個鑽削參數﹝轉速、進给率、鑽削模式及使用之切削液﹞，由實驗結果得到最小刀腹磨耗面積之最佳參數為轉速2500 rpm、進给率4mm/min、採用一般啄鑽法及切削液使用NEAT CUT 611。

The objective of this research is to investigate the optimal conditions for small hole drilling of Inconel 718 material by using Taguchi method. An image processing system has been developed by integrating a CCD camera, toolmaker’s microscope and personal computer to measure the flank wear area of the mini-drill in 0.4mm diameter.
Four drilling parameters, namely spindle speed, drill feedrate, peck drilling mode and cutting fluid are configured in the Taguchi’s matrix experiments. The result shows that the optimal drilling conditions for Inconel 718 small hole drilling in 0.4mm diameter are the combination of spindle speed 2500rpm, tool feedrate 4mm/min with common peck drilling mode and cutting fluid NEAT CUT 611.
