Motions of Cam

• Rise (R) One direction of output motion for a
  given period of input motion
• Fall (F) The opposite direction of rise for a
  period of input motion
• Dwell (D) No output motion for a specified
  period of input motion
• Combination of the motions RDFD, RFD, RF

Fundamental Law of Cam Design

• The cam function must be continuous through the
  first and second derivatives of displacement
  across the entire interval (360 degrees).
• Corollary The jerk function must be finite
  across the entire interval.

Discussion

• http//youtu.be/LEAqLu6gqVA
• Given the filling, plugging, and capping machine
  shown in the video. Discuss what kind of
  mechanisms are used. If you are designing the
  same machine, what will you use?

29
Design of Cam

• Always have continuous s, v, a
• Draw s, v, a, j diagrams to help design
• Consider 4-bar links, hydraulics and pneumatics
  as options.
• More cam designs are replaced by computer based
  control.

Homework (Due Dec. 5)

• Make a short (lt 5min) video explaining the
  mechanism of a push pen or a flip/slide phone.
• By project group
• You can use any tool for presentation
• Oral explanation
• Reverse engineering
• Hand sketch
• Solidworks drawing
• Animation
• Etc.
• Upload to Youtube or your choice of video service
  and send me a link.
