Abstract:
To promote the pose accuracy performance of a spatial parallel kinematic Mechanism (PKM) in service, a workshop oriented tolerance synthesis method based on design of experiment (DOE) is proposed, which involves two consecutive stages. In the first stage of DOE, the tolerance factor sensitivities are obtained according to initial tolerance settings with the consideration of the current manufacturing capacity, and the second stage of DOE makes use of them to produce multiple tolerance allocations which can adapt to current manufacturing capacity. A tolerance synthesis procedure is developed and integrated in tolerance design system for PKM. Comparing the results with peer method, the validity and practicability of this method is verified.
Key words: parallel kinematics mechanism (PKM) design of experiment (DOE) tolerance synthesis
