1. Cam Design and Follower Motion Analysis

2. Introduction Cams convert rotary motion into reciprocating or oscillating motion. They are widely used in engines and automation systems.

3. Objective To study cam design, follower motion, and the relationship between displacement, velocity, and acceleration.

4. Cam and Follower Types • Translating follower • Oscillating follower • Knife-edge, Roller, Flat followers

5. Basic Terms • Base circle • Prime circle • Pitch curve • Lift (stroke) • Pressure angle

6. Motion Types • Uniform velocity • Simple harmonic motion • Cycloidal motion • Constant acceleration and deceleration

7. Displacement Diagram Graphical representation of follower displacement versus cam angle.

8. Velocity and Acceleration Differentiating displacement gives velocity and acceleration curves, important for dynamic analysis.

9. Design Parameters Depends on required lift, follower motion type, cam rotation angle, and base circle radius.

10. Applications Used in internal combustion engines, textile machinery, and automation devices.

11. Conclusion Proper cam design ensures smooth operation, reduced wear, and precise motion control.
