Multi-axis cartesian guided parallel kinematic machine

A three-axis Cartesian guided parallel kinematic mechanism comprising;

• a frame;
• a base platform having a surface and mounted on and supported by the frame;
• a three-linear-axis Cartesian guiding mechanism assembly attached to the base platform and comprising;
• an x-y motion table having a guided motion plane and attached to the base platform in that the guided motion plane of the x-y motion table is parallel to the surface of the base platform surface;
• an open section defined on the x-y motion table;
• and
• a Cartesian z-axis movable arm having a guided z-axis motion and attached to the open section on the x-y motion table in that the guided z-axis motion of the z-axis movable arm is orthogonal to the guided motion plane of the x-y motion table;
• a motion platform firmly mounted on the z-axis movable arm;
• a tool head mounted on the motion platform;
• and
• three driving strut assemblies connected to the base platform at one end and to the motion platform at other end, and each driving strut assembly having:
• a telescoping mechanism to change the strut length;
• whereby when the telescoping mechanisms of the driving struts are actuated, the motion platform can be driven to a desired position in Cartesian workspace defined by the three-linear-axis Cartesian guiding mechanism assembly with a fixed orientation relative to the base platform.
