In this work, a systematic method using the theory of envelope to determine the geometry of Geneva mechanisms with curved slots is presented. In addition, the undercutting as well as double-point condition in the curve is investigated. The design charts free of undercutting and double point are also plotted based on the input driving angle and offset angle. A mock-up is built to demonstrate the feasibility and availability of the design theory. © 2008 Elsevier Ltd. All rights reserved.
