What is CAM and its classification?
Classification of Cams Disk or plate cam (Fig.
4.1a and b): The disk (or plate) cam has an irregular contour to impart a specific motion to the follower.
The follower moves in a plane perpendicular to the axis of rotation of the camshaft and is held in contact with the cam by springs or gravity..
What is a mechanical cam?
A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion. It is often a part of a rotating wheel (e.g. an eccentric wheel) or shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path.
What is radial cam?
A radial cam converts a rotational motion into a translational motion of the follower. … This Demonstration generates a cam profile starting from a displacement diagram defined by a set of locators. The first, second, and third derivatives of the follower’s displacement (velocity, acceleration, and jerk) are plotted.

What is CAM used for?
Computer Aided Manufacturing (CAM) is the use of software and computer-controlled machinery to automate a manufacturing process. Based on that definition, you need three components for a CAM system to function: Software that tells a machine how to make a product by generating toolpaths.
What things use a cam mechanism?
Cams are commonly used in engines to control valves (in which the valve is the follower), sewing machines, children’s toys and many other mechanical applications. The shapes of individual Cams are designed to produce specific types of motion.
How does cam mechanism work?
Mechanisms that utilize cams are typically designed to transform rotational motion into consistent reciprocating linear motion. … Car motors operate through a system of cams mounted on a cam shaft that open and close valves to regulate inputs (air and fuel) and outputs (exhaust) within the piston-cylinder assembly.
What is a cylindrical cam?
A cylindrical cam is a 3D cam which drives its follower in a groove cut on the periphery of a cylinder. The follower, which is either cylindrical or conical, may translate or oscillate. The cam rotates about its longitudinal axis, and transmits a translation or oscillation displacement to the follower at the same time.
What is side thrust in cam and follower?
Side thrust exists between the follower and the guide. Rate of wear is reduced. Side thrust exists between the follower and the guide. It is used where more space is available such as in stationary gas and oil engines and aircraft engines.
What are the different types of CAM?

Which type of follower is the most accurate?
Point or knife followers have a narrow point that sits on the cam. These are very accurate and low friction but are quick to wear away the pointed edge.
What is dwell period in Cam?
Rise is the motion of the follower away from the cam center, dwell is the motion during which the follower is at rest; and return is the motion of the follower toward the cam center. There are many follower motions that can be used for the rises and the returns.
What is a dwell?
verb (used without object), dwelt or dwelled, dwell·ing. to live or stay as a permanent resident; reside. to live or continue in a given condition or state: to dwell in happiness.
