碩士 === 國立交通大學 === 機械工程系所 === 94 === Continuous trajectory tracking has been well developed on machine tools of orthogonal nature. For non-orthogonally structured machine tools there is no comparable development. This study developed continuous trajectory cross-coupled contour tracking system, and contour tracking system with pre-compensation for 3RPS parallel machine tool. System structure is first constructed. Dynamic equations are derived by Newton’s method and by virtual work principle. A comparison of execution performance between systems from the two methods is performed. The constructed cross-coupled contour tracking system and the system with pre-compensation are evaluated by different types of trajectory. The developed systems are finally implemented on an empirical 3 RPS parallel machine tool. The empirical evaluation has shown that the developed systems are successful and effective.
