Cam Drawings

CAM Problem #1: Displacement Diagrams

Draw the complete Displacement Diagrams for the given Cam Problems.

Uniform Velocity CamProblem #1:

Description of Motion: Motion is to be unmodified straight line and uniform velocity which will give the follower a rise of 1.50" in 180 degrees and a fall in 180 degrees. Base circle is 3” diameter.

Modified Uniform Velocity CamProblem #1

Description of Motion:: Motion is to be modified straight line and uniform velocity whose radii are equal to one half the rise of the follower and will give the follower a rise of 1.50" in 120 degrees, dwell 60 degrees, fall in 90 degrees, and dwell in 90 degrees. Base circle is 3” diameter.

Harmonic Motion CamProblem #1

Description of Motion: Motion is to be Harmonic and will give the follower a rise of 2" in 180 degrees and a fall in 180 degrees. Base circle is 4” diameter.
