A cylindrical cam or barrel cam is a cam in which the follower rides on the surface of a cylinder. In the most common type, the follower rides in a groove cut into the surface of a cylinder. These cams are principally used to convert rotational motion to linear motion parallel to the rotational axis of the cylinder.

Cylindrical Cam
A cylindrical cam is a type of cam mechanism in which the follower reciprocates or oscillates in a plane parallel to the axis of the cam. It consists of a cylindrical-shaped cam with a follower that moves in a straight line or oscillates back and forth within the same plane. This type of cam is commonly used in various mechanical systems and machines.
Working Principle
The working principle of a cylindrical cam involves the rotation of the camshaft, which causes the follower to move in a linear or oscillating motion. The shape of the cam profile determines the type of motion generated by the follower. The follower is in contact with the cam surface, and as the cam rotates, it imparts a motion to the follower.
Advantages
- Simple design: Cylindrical cams have a relatively simple design compared to other types of cams, making them easy to manufacture and maintain.
- Parallel motion: The follower in a cylindrical cam reciprocates or oscillates in a plane parallel to the axis of the cam, which is beneficial in certain applications where this type of motion is required.
- Compact size: Cylindrical cams can be designed with a compact size, making them suitable for applications with limited space.
Applications
Cylindrical cams are widely used in various mechanical systems and machines, including:
- Printing presses: Cylindrical cams are used in printing presses to control the movement of the printing plate and paper feed mechanism.
- Machine tools: Cylindrical cams are used in machine tools to control the movement of the cutting tool or workpiece.
- Packaging machinery: Cylindrical cams are used in packaging machinery to control the movement of the packaging material and sealing mechanisms.
- Textile machinery: Cylindrical cams are used in textile machinery to control the movement of the yarn or fabric during weaving or knitting operations.
In conclusion, a cylindrical cam is a type of cam mechanism in which the follower reciprocates or oscillates in a plane parallel to the axis of the cam. It offers advantages such as a simple design, parallel motion, and compact size. It finds applications in various industries, including printing, machine tools, packaging, and textiles.
