The equivalent four-bar linkage of a disk-cam mechanism can be constructed through the application of Freudenstein's third theorem if the kinematic characteristics of the follower instead of the profile of the disk cam are specified. From such a process of reversing the usual construction order, the instantaneous radius of curvature of a disk-cam profile can be determined by means of the joint locations of the equivalent linkage. Based on this process, this paper presents a simple graphical method for determining the radius of curvature of a disk-cam profile. For most cases, the results obtained from this method are reasonably accurate.
