- Abstract:
- This study proposes a new coordinate measuring machine (CMM) based on a spatial 3DOF parallel mechanism. The use of this mechanism will potentially improve the stiffness, accuracy and efficiency. This paper describes the fundamentals and an experimental CMM. The influence of link layout on the measurement uncertainty, moreover, has been investigated analytically and experimentally. Obtained results show that the uncertainty has been decreased when the measuring point is in the extensional direction of the scale unit. Consequently, the Abbe’s principle can be applied to proposed parallel mechanism.
