PARALLEL CMM

Coordinate Measuring Machine using Parallel Mechanism




This study proposes a new coordinate measuring machine (CMM) based on a three-degree-of-freedom parallel manipulator. The proposed CMM has a number of advantages over the conventional CMM which uses an XYZ mechanism consisting of three mutually orthogonal slide mechanism. New PARALLEL CMM will improve the stiffness, accuracy and efficiency of the CMM.


FIg. This CMM is based on 3-DOF 3-SPR Parallel manipulator.



This is a prototype of "PARALLEL CMM". This CMM employs an aluminum truss frame with a compensation system for thermal and elastic deformations. Moreover, this 3 DOF parallel kinematic mechanism has a compensation system for joint runout and thermal and elastic deformation of the links. If you are interested in ths compensation system, see this page.
