Abstract
In this paper a novel 4 Degree-of-Freedom (DOF) parallel mechanism with the configuration of 4PUS-1RPU is first proposed, the mechanism is composed of four symmetrical driving chains and one central passive subchain. Based on the proposed 4-DOF parallel mechanism a 5-axis Hybrid Kinematics Machine (HKM) scheme is developed with an additional linear motion is combined, which can perform the 5-axis machining for freeform parts. The inverse kinematics of the 4-DOF parallel mechanism and the direct kinematics for the serial central sub-chain are then presented. The dexterity and the workspace analysis for the mechanism are also carried out. The dynamic characteristics of the PKM are investigated in detail. The simulation results show that the first four fundamental frequencies are the dominant factors that influence the dynamic characteristics of the developed PKM. The research provides the basis for the further parametric design with consideration of dynamic performances.
