6D: Slot-Cams


Usually, the motions of the cam and cam-follower are a function of the Master-Machine-Angle (MMA), even when their motions are calculated with inverse-kinematics.

A different design option is one in which the motion of the cam-follower is a function of the angular or linear position and motion of a machine part, and not the MMA.

When the motion of one Part is a function of the motion of a different Part, we call it Motion-Dependency.

Slot-Cams and the motion of the Cam-Follower usually use the Motion-Dependency design approach.

Note: Other terms for Slot-Cams are : Linear-Cam, Stationary-Cam, or Ramp-Cam.

Summary of this Tutorial

In this tutorial, we will design two Slot-Cams in which the motion of a cam-follower, a Rocker, is a function of the position of a sliding-part.

DESIGN 1: The sliding-part is a Slider. The motion of the Slider is specified directly at the input to the Motion-Dimension FB that identifies the Slider.

DESIGN 2: The sliding-part is a Part in a Dyad. The motion of the sliding-part is measured in-directly with a Measurement FB.
