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

2. MECHATRONICS ENGINEERING TECHNOLOGY 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.

4. MECHATRONICS ENGINEERING TECHNOLOGY Different Sections of CAM Lobe Rise SectionDwell SectionFall Section

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

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

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

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

9. MECHATRONICS ENGINEERING TECHNOLOGY 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. MECHATRONICS ENGINEERING TECHNOLOGY 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. MECHATRONICS ENGINEERING TECHNOLOGY 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.
