CASE STUDIES

In this chapter the output for different cases are discussed i.e. the cases formed when different types of motion curves for the followers (here only knife edge follower) are taken into consideration with the cam being only radial cam. There are even cases of having offset or not. The cases are as follows

CAM-FOLLOWER MOTION WITH OFFSET:

4.2.1. UNIFORM VELOCITY CURVE:

The output of the cam profile, for the motion curve being uniform velocity, for the given specifications of the cam is shown below.

Specifications of the cam:

Base circle radius of the cam: 80

Stroke or lift of the follower: 60

Outward stroke angle: 600

First dwell period angle: 450

Return stroke angle: 1200

Second dwell period angle: 1350

Offset distance of the follower axis from the cam centre: 20

The output i.e. the displacement diagram and the cam profile are:
