Abstract
This invention relates to the parallel structure of a spatial 3-axis machine tool with three degrees of freedom (3 DOF), which have two translational DOF and one rotational DOF. The machine tool includes a base, a mobile platform to which a tool may be attached, and three kinematic legs. Two of the three legs are in a same plane, and each have one 3-DOF spherical joint and two 1-DOF joints. The third leg has one 1-DOF joint and two universal joints. Compared with traditional machine tools, this invention possesses several advantages such as simple structure, high stiffness, low inertia, low cost, and high speed.
