ABSTRACT:
A composite mechanism multi-axis machine tool includes an orthogonal coordinate feeding axis mechanism and a parallel type spatial linkage mechanism. The orthogonal coordinate feeding axis mechanism has two orthogonal platforms to provide two dimensional motion vectors. The parallel type spatial linkage mechanism has three sets of linear feeding modules engaging with a base frame for holding a main spindle which further holds a tool cutter. The parallel type spatial linkage mechanism provides one dimensional motion and two dimensional rotation for the tool cutter. A controller is provided to control and coordinate the movements of the orthogonal coordinate feeding axis mechanism and the parallel type spatial linkage mechanism. It reduces accumulation of inertia and tolerance effect, and rigidity deficiency of conventional orthogonal coordinate multi-axis machine tool, and overcomes the problems of conventional hexapod parallel type spatial linkage mechanism such as difficult for position tuning, small working space, complex control system and high cost.
