The radius of curvature of a cam profile is an important factor that affects the working life of cam mechanisms. Based on flexible motion curves using parametric polynomials developed earlier, a method for maximizing the minimum radius of cam curvature using a nonlinear programming technique is presented. The relation between the radius of curvature of a cam and the kinematic features of the corresponding motion curves is discussed. Examples are presented to illustrate the method.
