Chapter 6 Profile Cam Design time-motion program to provide a dwell _.mm ".. The cam profile will be laid out using 10° plotting intervals. Assume that the cam rotates with constant angular Problem 6-1 Design a simple harmonic cam at zero lift for the first lift for cam angles from 0 of the motion cycle and to dwell at to velocity. 0° 90° 80 270° Cam Angle, Cam follower data using simple harmonic motion for rise and return | 10° | 20° | 30° | 40. | 50. | 60° 170° T40 Cam anglepl 0° Displacement y Cam angle 90' | 100. | 110 120-130 140. 150. 160. 170.
