BASIC CURVES

The follower velocity and acceleration are of pertinent concern in most machines since proper design requires accurate analysis and control of the velocity and acceleration curves. In general, the higher the speed, the more critical becomes the investigation. This is especially true of the acceleration curve which is the determining factor of the dynamic loads and vibrations of a cam-follower system. For years mathematically related basic curves have been found convenient .These curves have been proved popular from a standpoint of ease of layout, reproduction analysis and control.
