The slider-crank linkage is ubiquitous in machinery, from the piston/connecting rod/crankshaft in an IC engine to the flywheel/connecting rod/ram of a mechanical press. Function generation is the method by which slider-crank linkages may be designed to have a desirable set of kinematic properties. The kinematic properties are defined by the curve that relates the rotation of the input link of the slider-crank to the distance of slide produced at the output. The well-established methodology for slider-crank function generation states that five points can be selected to generate one of these curves. The five point methodology does not guarantee that the resulting linkage includes an input link that is capable of a full rotation, a necessity in most practical problems. Moreover, the methodology can result in linkages containing circuit defects. The problems of required full rotation and of avoiding circuit defects are addressed in this research. This research also addresses constraints on velocities and accelerations in the design process.
