本文旨在探討使用單點式鑽石修整器修整平面磨床的砂輪時，修整深度與修整進給對後續磨削加工之工件表面粗糙度的影響。研究中參照一般生產現場使用平面磨床的操作程序與各種加工參數之條件，進行實驗研究分析。結果發現，修整進給大於0.17mm/rev時，其工件表面粗糙度就會隨修整進給的增加而增加。工件之表面粗糙度亦隨修整深度的變大而變差，但當修整深度大於修整進給與修整器外形所形成的砂輪表面最大波峰時，表面粗糙度變化趨於緩和。當磨削深度由到小變大，磨削進給由慢到快時，表面粗糙度會隨著增加。

The thesis investigates the effect of the dressing feed, and the depth of dressing on the surface roughness of workpieces by using a single-point diamond dresser to dress wheel. Experimental investigations were carried out by using the same operating sequence and variant process parameters of surface grinding process with those using in the factory. The results show that surface roughness of workpiece becomes worst as the dressing feed and the depth of dressing increase as dressing feed is over 0.17mm/rev. But when the depth of dressing is over the crest point of surface wheel, formed by the shape of dresser and the dressing feed, the variation of the surface roughness getting obvious. At the same time the surface roughness of workpiece getting bad as the depth of grinding and the grinding feed increased
