隨著科技的進步與時代的改變，製造業對工作母機精度的要求也愈來越高，所以在工具機出廠前必須先進行誤差檢驗並加以補償，以提高精度，因此了解工具機的誤差來源及補償的方法即為當下不可忽視的課題。
本論文的主旨在利用齊性座標轉換矩陣，推導三軸CNC銑床之誤差模型，接著透過6D雷射干涉儀量測三軸工具機三線性運動軸之定位誤差，並藉由ISO230-6之對角量測路徑進行誤差的模擬，完整建立三軸工具機之誤差模型，此一已知誤差模型可作為未來建立補償機制的基礎。

Because of the progressing of the technology and the changing of the time, to acquire a better accuracy of working machine for a manufacturing industry is becoming more important day by day; therefore, we must check and fix errors of a working machine to raise its accuracy before it leaves the factory. That is, nowadays to understand the origin of error of a working machine and the fixing ways of it are necessary.
The topic of this thesis is to use the Homogeneous Transformation Matrix to make three axis machining center and to build an error model in function. And then we will operate the 6-degree- of —freedom laser system to measure the positioning error in three numerically controlled axis of three axis machine. In the meantime, we will map a complete error model of three axis machine by practicing an error drill from the diagonal displacement test, ISO230-6. The consequence we make from this error model can be the map of the basic fixing system in the future.
