# What type of motion does a cam have?

## What type of motion does a cam have?

A cam changes the input motion, which is usually rotary motion to a reciprocating motion of the follower. They are found in many machines and toys.

### What is simple harmonic motion in cam and follower?

Simple Harmonic Motion: Since the follower moves with a simple harmonic motion, therefore velocity diagram consists of a sine curve and the acceleration diagram is a cosine curve. velocity of the follower is zero at the beginning and at the end of its stroke and increases gradually to a maximum at mid-stroke.

What is SHM cam?

Simple Harmonic Motion (SHM): Simple harmonic motion curve is widely used since it is simple to design. The curve is the projection of a circle about the cam rotation axis as shown in the figure.

How does a round cam move?

Circular cams use an off-centre pivot to cause the follower to move up and down. The follower will rise and fall by a reasonably large amount. These can be seen in pistons, for example on steam engines.

## What is cam function?

A cam is an oscillating 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 the equation of cam?

Cam Calculation Equations

Lift f y (z) = (6z 2 – 15z + 10) z 3
Speed f v (z) = (z 2 – 2z + 1) 30z 2
Acceleration f a (z) = (2z 2 – 3z + 1) 60z
Pulse f j (z) = (6z 2 – 6z + 1) 60

What is cam angle?

A. During which the follower returns to its initial position. Of rotation of the cam for a definite displacement of the follower. Through which, the cam rotates during the period in which the follower remains in the highest position.

What is cam explain?

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 are cam elements?

Cams are made in a variety of forms, such as: (1) a rotating disk or plate with the required profile; (2) a plate with a groove cut on its face to fit a roller on the follower (face cam); (3) a cylindrical or conical member with a follower groove cut around the surface; (4) a cylinder with the required profile cut in …

### How does cam mechanism work?

A cam and follower mechanism is a profiled shape mounted on a shaft that causes a lever or follower to move. Cams are used to convert rotary to linear (reciprocating) motion. As the cam rotates, the follower rises and falls in a process known as reciprocating motion.
