Static accuracy enhancement of redundantly actuated parallel kinematic machine tools
Abstract
Redundantly actuated parallel kinematic machines are a new type of mechanism derived from classical parallel kinematic machines by adding one or more redundant links. In this dissertation, new calibration methods have been developed to improve the static positioning of such machines. These methods are based on geometrical and elasto-geometrical modeling. The latter takes into account the elements' elastic deformations due to the redundancy.
