  1. Concepts of CAM Prepared by: Gautam Agarwal, M.S (Technology)-PUC

  2. What is CAM? • A machine element having a curved outline or a curved groove, which by its oscillating or rotational motion • Gives a pre-determined specified motion to another element with which it is in contact, called the Follower.

  3. CAM operation

  4. Different Sections of CAM Lobe

  5. Rise Section • Drives the follower upwards, its profile determines how quickly the CAM follower will be lifted

  6. Fall Section • The part that lowers the follower, its profile determines how quickly the CAM follower will fall.

  7. Dwell Section • Is the part that allows the follower to remain at the same level for a significant period of time.

  8. Applications of CAM Operation • Printing Press • Shoe Machinery • Textile Machinery • Gear-cutting Machines • Screw Machines.

  9. Electronic CAM • Identical to Mechanical CAM • Slave axis or the follower axis follows the master axis. • Achieved using : • MASTER AXIS • SLAVE/FOLLOWER AXIS • CAM operation is done by defining set positions of master axis and slave axis through CAM points.

  10. CAM Points • Reference points for the Electronic CAM operation and could be understood as a set of point which defines the positions for the Master Axis and Slave Axis. • The Slave axis follows Master Axis based of these CAM points.

  11. Electronic CAM Example • For Example- A CAM point defines as (X=0.5, Y=0.5) where unit is 1 revolution means that when the Master (X) is at 0.5 Slave (Y) should go 0.5 turns.

  12. Advantages of Electronic CAM • Accurate • Flexible • Programmable • Faster • Smooth Operation • Less Expensive
