本研究主要使用CBN電鑄砂輪對鎳基合金Inconel 718進行實驗，並配合傳統磨削機制與放電磨削技術，進行磨削力、磨削過後之工件表面粗糙度與砂輪磨耗之探討。本實驗主要可分為三大部分：（a）利用動力計在磨削過程中，量測砂輪切線方向的磨削力，同時由電腦的資料分析，了解放電磨削機制對於磨削力之改善及影響；（b）分析放電磨削技術過後的表面粗糙度與砂輪磨耗的影響；（c）討論迴歸分析於放電磨削機制的適用性。由放電磨削實驗的結果可得知，導入放電能量可有效的降低磨削力約34 %，可改善其表面粗糙度約9 %，但砂輪磨耗則有增加之趨勢。而經由迴歸分析所建構之數學模式最大誤差可控制在25 %內。

In this study, the grinding process has been investigated in the machining of nickel-based alloy Inconel 718 with traditional grinding and abrasive electrical discharge grinding (AEDG) technology. Moreover, grinding force, surface roughness and grinding wear will be discussed in this study. Three parts are discussed in this study: (a) using a dynamometer to measure the tangential grinding forces of grinding wheel and to analyze the data with PC, understanding the effects and improvements by introducing AEDG technology; (b) analyzing the surface roughness and grinding wear after abrasive electrical discharge grinding; and(c) discussing the feasibility of regression analysis on the AEDG. In the results of the AEDG experiment, grinding with electrical energy can effectively reduce the grinding force about 34%. The surface roughness is improved about 9%, but grinding wear is increased. We found that the maximum error of regression analysis prediction can be controlled within 25%
