6. Cam By Dr. Hong Zhang

7. Cam and Follower

8. Different Motions Translating Follower Oscillating Follower

9. Different Constraints Form-closedForce-closed

10. Cam Followers In An Engine

11. Different Followers Flat-faced follower Roller follower Mushroom follower

12. 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

13. Displacement Diagram

14. S-v-a(-j) Diagram

15. 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.

28. 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.

31. Homework (Due Dec. 5) Make a short (< 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.
