Synthesis of Oldham Mechanisms for Three-Finitely Separated Positions

This paper deals with the synthesis of Oldham mechanisms with inclined and/or orthogonal slots for three-finitely separated positions. In particular, the pole triangle and its circumcircle, along with the corresponding mirror circles, are determined in order to apply the synthesis procedure. The epitrochoid coupler curves are also determined and implemented in a whole synthesis algorithm, which has been validated by means of several significant examples. Moreover, a suitable comparison with the corresponding infinitesimal motion is carried out.
