A new approach to the function synthesis of the planar mechanisms is presented, which includes four bar linkage, crank slider and its invert mechanism, to generate the given function by means of searching a circle point on the relative link or an enveloped circle on the relative base. Then, the unified mathematic model is set up to be a circle fitting and saddle point planning. Meanwhile, orthogonal experimentation and distribution law of coupler curves are adopted to solve such problems as selecting initial point, capturing global optimal solution. Finally, some examples are given to show the feasibility and the validity of the approach.
