摘　　要：介绍了一种新型立卧转换式三杆混联机床3-TPS(RRR)混联机床,对该机床的结构进行了分析.该机床具有工作空间大、立卧转换、五轴联动、五面加工等特点,并具有加工中心的功能.给出了该机床在实现三轴、四轴加工时的坐标变换过程及变换方程,给出了实现三轴、四轴加工时的后置处理算法及数学模型,并对该机床的立式加工和卧式加工两种情况进行了分析,给出了算法和显式方程.A new horizontal-vertical conversion hybrid machine tool, 3-TPS hybrid machine tool is introduced with its configuration analyzed. The hybrid machine tool not only has such advantages as large workspace, horizontal-vertical conversion, simultaneous motion of five axes and five-sides machining, but also serves the function of machining center. The coordinate transformation process and transformation equations of 3/4-DOF machining operation are given, as well as the postprocessing algorithms and mathematical model established for the implementation of such operation. Analyzing both the horizontal and vertical machining processes, the computational algorithms and equations are given in explicit forms.
