本實驗的目的是探討圓柱研磨對於SUJ2合金鋼的最佳化研究，挑選的加工參數為砂輪修銳速率、進給率、工作轉速、磨削深度這四項，實驗機台以銡翔CNC圓筒磨床機，實驗進行後，分別量測工件表面粗糙度與真圓度的值。使用反應曲面法(response surface methodology, RSM)的二階數學模組以及結合連續近似最佳法(sequential approximation optimization method, SAO)，獲得表面粗糙度及真圓度與加工參數之間的關係，其中以砂輪修銳速率在加工特性中影響最為顯著，透過所獲得的最佳加工參數，其最佳化表面粗糙度值與初始值的表面粗糙度值Ra相比較改善了36.9%，其最佳化真圓度值與初始值的真圓度值相比較改善了6.9%。

The purpose of this experiment is to explore the optimization of cylindrical grinding process parameter of SUJ2 steels by response surface method (RSM). The selected grinding parameters are grinding wheel dressing speed, feed rate, speed of work and depth of grinding. The experimental machine used is SHM CNC cylindrical grinding machines. After the experiment, the surface roughness and roundness of work were measured. The relationship between processing parameters and surface quality were obtained by using RSM approximate optimal method for second order mathematical module and continuous sequential approximation optimization method (SAO). The results shown that the dressing speed of grinding wheel is the most significant parameter. The optimum predicted value of surface roughness compared with that of initial value was 36.9% reduced. The results shown that the dressing speed of grinding wheel is the most significant parameter.The optimum predicted value of roundness compared with that of initial value was 6.9% improved.
