Cam and Follower
Cam and Follower are a pair of higher-level links that are that are used to move links either frequently or in a direct manner. The purpose of this is to lessen the chance of errors. The third century saw the introduction of the device referred to as the camera was developed in the hands of Hellenistic automated machines powered by water.
Mechanisms for cams and followers are typically employed for internal combustion engines to control the valves. In addition the mechanism of cams and followers is frequently utilized by engineers as component in the I.C.E timer system. This mechanism is used in the automotive industry to control fuel pumps.
The mechanism is created by the combination of three parts. A driving member is referred to as the cam, and a frame that houses the cam, and the follower. It is controlled by the frame and the member that drives is designated to be the following member.

What is a Follower?
The follower is an oscillating or rotating component of a machine that tracks the movements of the cam via direct contact. When a cam is in a reciprocating motion The follower rotates in a parallel direction to the cam's its axis.
It is part of the machine predominantly guiding a cam which can oscillate or rotate in motion. The rotary motion that the cam is into a reciprocating as well as oscillating movement.
What is a Cam?
Cams are a rotating piece that gives oscillating or reciprocating movement to the following device through direct contact. The cam is used to convert the motion from linear to rotary.
It is an element of a machine which is a rotating electric wheel or a shaft which strikes the lever at various points along its circular course. It is commonly employed in a steam hammer as a basic tooth to transform power pulses into steam hammers.

Types of Cams
Below are the various kinds of cams that are described below:
1 Wedge or Flat Cam
The wedge, also known as a flat cam is straight edges to allow for an individual movement for the followers.
2 Disc or Plate Cam
The plate cam or disk is not a straight form to provide an identifiable move to the following.
3 Spiral Cam
The spiral cam is either a semi-circular or spiral cut-out contour. The cam moves in a circular motion, and the follower follows perpendicularly to the axis of the cam.
4 Cylindrical Cam
In a cylindrical cam, it is made up of a groove on the cylindrical surface. the follower is moved along the surface of a cylindrical cylinder that is parallel to the axis the cylindrical.
5 Heart-shaped Cam
The heart-shaped cam resembles an unsymmetrical heart. It's utilized to rotate a shaft in order to maintain the camera in a fixed location by the pressure of the roller.
6 Translating Cam
The translating cam is made up of a groove or a contour plate. The follower is oscillating on top of the plate. The contour plate or groove determines the direction that the following device.
7 Snail Drop Cam
A snail-drop cam can be used to create a timekeeping clock mechanical so that the daytime advancement system can be running at midnight, and a follower for longer than 24 hours, by putting the camera in a spiral direction. The process is completed by a sharp stop. The following person will be dropped down and begin the following day ahead of time.
8 Conjugate Cam
The cam that is conjugated has an operation with two distinct oscillating rollers. The followers serve as a measuring fixture. If the cam turns in a certain direction, the shift of the angle that is not optimal between the two arms could indicate the change in the error in the profile of the cam.
9 Globoidal Cam
In terms of shape the globoidal cam is among the most complicated cams. The surfaces that work for global cams are their contact surface with rollers.
10 Spherical Cam
The spherical cam mechanism is an alternate to the bevel gears because they have less backlash and less friction loss.
