Structural Design and Kinematics Analysis of Oblique Crossing 3DOF NC Spindle
Based on the study of 3R oblique non-spherical wrist and the analysis of the NC machine spindle’s function, the concept of a oblique crossing 3DOF NC spindle was offered and the 3D model of this 3DOF NC spindle was made with Solidworks software. At the same time, the kinematics model of this 3DOF NC spindle was setup with D-H parameter method and the kinematics & workspace of this 3DOF NC spindle were analyzed and simulated. Simulation results indicated that this 3DOF NC spindle, with compacted-structure, low inertness and considerable flexibility, could be in any gesture in the 3D space, and could expand the work range of the NC machine.
