Abstract

This paper analyzes a 3-DOF Parallel Machine tool with Actuation Redundancy (PMAR) which is designed based on the 3RPS parallel mechanism with a redundant SPS leg. The Jacobian matrix with four rows and three columns is proposed. Based on Newton-Euler equation, the dynamic model of this mechanism is established. The compatibility equation must be found to solve the dynamic problem due to actuation redundancy, as makes the dynamic analysis difficult. This paper presents the compatibility equation using Castigliano's second theorem. The conclusion will be significant for detailed research and redundant control of this mechanism. The ultimate goal is to use these results to design a prototype to grind drilling tools.
