Unformatted text preview: It thus follows that the following equation must be satisfied for all Design equations (11) (12) A condition for avoiding cusp in the cam profile cusp By substituting 11 and 12 in 13 we find that in order to avoid cusp in the profile of the cam the following equation must be satisfied for all θ If there is a point of cusp in the cam then the contact between the cusp and the follower is not instantaneous. Therefore the mathematical condition describing the existence of a cusp is that for some = = d dy d dx ( ) ( ) > ′ ′ + + f f C (13) Design equation (14) for all...
