Abstract: Described in this paper are general methods for precisely calculating the maximum pressure angle and its acting position as well as the method to determine fundamental dimensions in accordance with allowable pressure angle under conditions of applying complicated types of follower motion to the synthetical or simplified design of planar cam (-link) mechanisms with translating and oscillating rolle-rended follower.The formulae appeared in the article are suitable for calculation by a hand-calculator oran electronic computer.Several calculating examples are presented and the influence of various different types of follower motion on the maximum pressure angle and its precise acting positon under given conditions emerged from these examples is analysed at the end of this article.
