摘要: 
為了迎接高速切削與高精密化的加工技術,增進軸向進給系統的
定位精度,是提昇CNC工具機在二度及三度空間輪廓加工技術最基本的
要求項目。
本文採用臺中精機Vcenter-65立式綜合加工機,配合FANUC公司
先進的控制補償技術,在不改變現有機械系統條件的前題下,針對XY
軸電控系統的伺服特性,並利用Renishaw的循圓量測系統,引入田口
方法靜態特性,調整控制器內部伺服參數最佳的調整值,使機械與電
控系統有最好相互匹配,提高定位精度。
本文中亦使用田口方法,探討各參數因子在其他參數條件變化的
情況下,對機器之循圓精度的影響效果,同時找出重要的影響參數,
並選出最佳的組合條件,進行對改良工具機之動態輪廓精度。

Facing the progressing technology of high-speed and high-precision machining techniques, the basic requirements in 2-D and 3-D CNC machine tools are promoting the positioning accuracy of axial transmission system.
To get mutual matching and promoting the positioning accurary in mechanical and electronic systems, the article adopts Taichung Machinery Work Co. Vcenter-65 machining center that assorted FANUC advanced control-compensation techniques with focusing on adjusting the characteristics of the servo system that under the condition of unchanging existing mechianical system. In the meantime, the circular testing experiment for the best servo prameters of the controller were planned by using the Taguchi method.
This article also adopts the Taguchi method to find out the effect of the accuracy of circular tests that is caused by each factor working under the changing condition of other factors. It, meanwhile, to find out the important effective factors, choose the best level combination to improve the machine contouring accurary as well.
