摘要: 
本論文研製之五軸工具機旋轉軸雷射量測系統,用以取代一般市面上接觸式及光干涉式量測系統。系統分為兩部分,旋轉軸精度量測系統與貓眼反射鏡。第一部分為旋轉軸精度量測系統,此探頭使用一組雷射二極體做為光源,搭配兩組四象限光位置感測器以接收訊號,可量測貓眼反射鏡在三維空間中的座標訊息。第二部分為貓眼反射鏡,使用一折射率為2之球透鏡,在半球面上蒸鍍鋁材料做為反射層,用來傳達機台之誤差資訊。本量測系統將針對五軸工具機之旋轉軸進行旋轉組裝誤差及定位精度量測,並對工具機進行BK-2檢測。
本量測系統優點價格低廉,無須使用昂貴的系統零件,架設容易且操作簡單,可有效縮短量測時間並提升效率,整體系統成本低廉,元件尺寸小,且系統量測精度高,其量測系統定位誤差為+/-1.5 um內,解析度可達50 nm。

A procedure is an electro optical measurement rotary accuracy and position accuracy of five-axis machine tools, it is designed to replace the contact type system and light interference measurement system, this system is divided into two parts, first part is rotary axis accuracy measurement system which uses laser diode as system light source and quadrant photo diode to receive light single that can detect the three-dimensional position of cat''s eye reflector . The Second part is cat''s eye reflector which uses ball lens of n=2 with coating aluminum to hemispherical that is used to convey message of the table position on the machine tool. This measurement system will be detected the rotary accuracy and position accuracy of the five-axis machine tools, and use tip tracking for machine tools.
The advantage of this system is low price without expensive optical components, the installation process of it is convenient and quickly, erection of it is sample and reduces the measurement time significantly. This system has low-cost and the components are very small, high measurement accuracy, and position error of system about +/-1.5 μm, system resolution can be measured to 50nm.
