The motion along a spatial path should be set for machining tools to cut complex internal surfaces with variable cross sections of the machine elements. Spatial mechanisms of the second family, which have four relative motions within absolute Cartesian space of coordinate and necessarily produce a screw motion, are the most suitable means of realizing this aim. Kinematic schemes of the spatial mechanisms for cutting internal surfaces have been described for the first time in this paper. These mechanisms are protected by patents of the Russian Federation. Developed mechanisms have been kinematically investigated by the identification of motion paths of their output links with machining tools. The results of these investigations allow analysis of the tools’ motion, optimization in their construction and the use of relevant parameters, and designing their motions to obtain specified surfaces of machine elements.
