CHAFE

Optimization of Planar Cam Mechanisms with Roller-Followers,Angeles and López-Cajún (1984b, 1988) showed that the cam-size minimization problem for oscillating followers, whether of the flat-face or the roller type, reduces to the solution of a quartic equation. Below we expand the methods proposed in the last two references, in a unified framework, in line with the methods delineated in Chapter 4.

Introduction,xed frame. Sometimes, an intermediate element is introduced between the cam and the follower with the purpose of improving the mechanism performance. This element is called the . because function is to produce a pure-rolling relative motion between the cam and the follower. The purpose of a cam mech

The Displacement Program,an easy-to-handle, smooth-enough function of the angle of rotation of the cam disk, representing the displacement of the follower. The second stage deals with the synthesis of the cam profile itself. The synthesis of the displacement program has been traditionally based on a limited set of functions
