In mechanical engineering, engineers often use a higher pair links mechanism that is renowned as Cam and Follower Mechanism. This pair of higher links are used to move links spontaneously or periodically. Although, cam and follower mechanisms are also used by engineers for ensuring zero or minimum degree of error.

A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion. The cam can be a simple tooth, as is used to deliver pulses of power to a steam hammer , for example, or an eccentric disc or other shape that produces a smooth reciprocating back and forth motion in the follower , which is a lever making contact with the cam. A cam timer is similar, and were widely used for electric machine control an electromechanical timer in a washing machine being a common example before the advent of inexpensive electronics, microcontrollers , integrated circuits , programmable logic controllers and digital control. The cam can be seen as a device that converts rotational motion to reciprocating or sometimes oscillating motion. Cams can be characterized by their displacement diagrams, which reflect the changing position a follower would make as the surface of the cam moves in contact with the follower. In the example shown, the cam rotates about an axis. These diagrams relate angular position, usually in degrees, to the radial displacement experienced at that position.

It is used to decrease the degree of error. In the third century, the device known as the cam was produced by Hellenistic water-powered automata. In addition, the device was found in al-Jazari design in the 4th century.

Kinematic Analysis of the Roller Follower Motion in Translating Cam-Follower Mechanisms

The main purpose of this work is to present a complete kinematic analysis of the roller motion in translating cam-follower mechanisms with translating roller followers. The main kinematic variables of the roller are the angular velocity and angular acceleration.
When the two links are connected either along a line or at a point, it is called a higher pair. Two such higher pair mechanisms will be included in a cam-follower system. A higher pair mechanism is known as cam and follower. For the smooth functioning of a cam-follower mechanism, it is imperative that the follower should move smoothly without requiring too much input power, which means the follower should not jam, during its movement. In an IC engine the valves have to be kept open; first, then close it and keep it closed, all these timing operations can be easily set by having cam-follower mechanisms. In the case of linkages, we study about planar linkages or two- dimensional linkages and more.
Dhande, S. June 1, June ; 2 : — An analytical approach to the kinematic analysis of certain types of constant-breadth cam-follower mechanisms has been presented in this paper. The objective of the kinematic analysis is to provide closed-form parametric equations for the displacement, the velocity, and the acceleration of the follower driven by a constant-breadth cam profile rotating at a uniform angular velocity. The follower surface is considered to be a flat-face and the follower motion may either be translatory or oscillatory, or translatory as well as oscillatory. The proposed approach is general in nature and can be used for the kinematic analysis of any profile-closed higher-pair mechanism.
