A multi-axis Cartesian guided parallel kinematic machine has a frame, a base platform, a multi-axis Cartesian guiding mechanism assembly, multiple driving strut assemblies and a motion platform. The motion platform is connected to the base platform through the driving strut assemblies and the multi-axis Cartesian guiding mechanism assembly. The multi-axis Cartesian guiding mechanism assembly has multiple linear guiding mechanisms and rotary guiding mechanisms that are in-serial linked and arranged in orthogonal to each other according to the Cartesian coordinate system. The multiple driving strut assemblies are in-parallel connected to the base platform and the motion platform using pivot joints. Each driving strut assembly is a telescoping strut assembly or a sliding strut assembly. When the driving strut assemblies are actuated, the motion platforms can be driven to a desired position in the Cartesian workspace with a controllable platform orientation relative to the frame.
