五面加工混联机床概念设计（Conceptual Design of a Novel Hybrid Machine Tool with Five-face Machining Capability）
混联机床 3-PRS主轴部件 X-Y并联驱动平台
2009/9/25
提出一种五面加工的六轴混联机床的设计方案。以典型刀具和工件加工时的相对运动要求为输入，得到刀具和工件的位姿关系矩阵，用机床的串并联运动功能模型实现了刀具和工件的位姿关系。六轴混联方案中，主轴部件一侧采用可实现Z轴移动和A及B摆动轴进给的少自由度3-PRS并联机构，工作台一侧采用X-Y并联驱动和C轴数控转台的串联机构。安装在3-PRS并联机构动平台上的主轴部件通过倾斜布局、合理构件（组件）设计使刀具...
