Groove Cam - Educational model

My Educational Mechanical Examples SeriesThis model is one of my educational mechanical mechanism examples on 80mm x 80mm base plates.You can find all models of the series in this collection => [Mechanical Mechanism Examples] The present modelThis is an educational model of groove cam, which can convert a rotational motion into an arbitrary rocking motion.Brief DescriptionA cam changes the position of a follower as it rotates, and by designing the cam profile appropriately, the follower can be made to follow almost any desired motion. In ordinary plate cam mechanisms, the follower must be pressed against the cam surface by an external force such as gravity or a spring.In contrast, a groove cam—like the one in this model—uses a groove-shaped track to constrain the follower. Because the follower is captured inside the groove, no additional force is required to keep it in contact with the cam, and its motion is fully guided by the geometric shape of the track. In this model, the cam profi
