旋盤被廣泛應用為工作母機第四軸之連續定位裝置。目前國內廠商均採用齒輪系為減速裝置，為提升旋盤之定位精度、負載與效率，本研究提出一以滾子輪式凸輪作為減速裝置之旋盤，期能由滾子輪式凸輪之理論推導，發展為產業之實際應用。
本論文首先建立滾子輪式凸輪減速裝置之形式及設計參數，然後針對此裝置做機械特性之分析，最後製作一旋盤，並量測旋盤之性能。

Rotary tables are generally regarded as the forth axis of machining tools. Traditionally, gear sets are used as reducers in the rotary tables. In order to improve the positioning accuracy, load and efficiency of rotary tables, a rotary table which applies the roller gear cam reducer is proposed. From the deduction of the theory, applications of roller gear cam reducers in the industries can be achieved. This thesis is focused on developing the procedure as follows:
Firstly, the type of roller gear cam reducer and design parameters are identified. Secondly, the mechanical characteristics of the device are analyzed. Finally, a rotary table is designed and implemented to investigate the performance of the of the roller gear cam rotary table.
