In 1, we saw that it is possible to construct a cam by blending crude increments and observing its appearance This method is not acceptable in the design of today s cam machinery Now it is necessary to provide accurate mathematical information for the cam characteristics of displacement velocity, acceleration, and sometimes the jerk In so doing one can interpret and control the ultimate design performance Also, the higher the cam speed, the more critical is the investigation This is especially true of the acceleration data which is the important determining factor of the dynamic loads on cam-follower systems This chapter presents mathematically established basic curves which are the rst selection to establish the follower action They are easy to analyze and manipulate Cams can be designed for any acceptable curve or shape Appendix A lists various kinds of geometric curves that have been used in the past They include the ellipse, parabola, hyperbola, logarithmic spiral, and involute of a circle Alternative combinations of these curves combined with the circle and straight line have also been constructed (see 15)

As previously indicated, a cam can be considered similar to a wedge having a cyclical rise and fall which establishes the motion of the follower In all cams, the displacement of the follower is given by the mathematical relationship y = f (q ) in (21)

where q = cam angle rotation in radians However, since the cam rotates at a constant angular velocity, the displacement can also be written as y = g(t ) in and q =wt (22) (23)

where t = time for cam to rotate through angle q, sec w = cam angular velocity, rad/sec By the use of Eq (21) the follower characteristics can be normalised (dimensionless) as follows: The cam pro le is usually given as a function of the angle q Thus y = follower displacement The instantaneous angular rate of change of displacement y = dy = follower velocity dq (25) (24)

By the use of Eq (22) the follower characteristics can be expressed as direct time dependent as follows: The follower velocity can be written as y = dy dt = ( dq dt )( dy dq ) = w ( dy dq ) = w y the follower acceleration y = d 2 y dt 2 = d dy d d dy dq w =w =w dt dq dq dq dq dt (29) (28)
