Mechanisms, such as linkages with rotational or prismatic joints, cams, non-circular gear pairs and a variety of other mechanism types are classical mechanical means for generating complex movements of work elements in processing machines and thus often the "heart" of a machine for the performance of a certain technological process. As an alternative to these "classic" mechanisms, positioncontrolled servo drives with programmed motion control ("Motion Control Systems" or "MCS") are increasingly being used to solve demanding motion tasks. Sometimes, however, a combination of an MCS with a linkage can be a particularly favorable solution. Awareness of these opportunities that are presented here in the necessary brevity and in much greater detail in the VDI guideline to be published soon, is lo encourage the design and development engineer to consider in appropriate cases such combination of solutions. Thus, some motion tasks may be solved easier or more elegantly than in the case of being restricted to just using an MCS without considering any mechanisms such as linkages, cams, linked gears or combinations thereof. Parts of this paper have been taken from a former German paper published in 2014 (Corves in VDI-Berichte 2237:27-39 (2014).
