In this paper, synthesis of Stephenson Ⅲ planar six-bar linkage for rigid body guidance is studied by comprehensive application of precision point method and optimization method. Firstly, the linkage is decomposed into two parts: a dyad and a four-bar linkage. Then, the dyad is synthesized using optimization method and the four-bar linkage is synthesized using precision point method. Finally, the suitable Stephenson Ⅲ planar six-bar linkages are obtained by combining the obtained dyads and four-bar linkages. An example is given and all possible six-bar linkages are obtained. The method used in this paper can also be used to solve synthesis problems of other complex planar linkages.
