摘要：

This paper presents a novel four-degree-of-freedom (4-DOF) partially decoupled parallel mechanism which can generally be used in machining processes, but here, it is particularly designed for turbine blade machining. Forward and inverse kinematic formulations have been derived for proposed mechanism, and using Jacobian matrix has proved that the mechanism has no singularity in its workspace. The workspace has been analyzed using a geometric approach, and the required stroke lengths of mechanism's actuators for the defined task have been acquired.
