What we have learnt
- A cam imparts reciprocating or oscillating motion to a follower.
- The design of motion diagrams is essential for analyzing follower dynamics.
- Pressure angles and undercutting are crucial factors in cam design.
Key Concepts
- -- Cam
- A rotating machine element that imparts reciprocating or oscillating motion to a follower.
- -- Follower
- An element that follows the motion of the cam, which can be of various types such as knife-edge, roller, flat-faced, and spherical.
- -- Pressure Angle
- The angle between the direction of follower motion and the normal to the pitch curve, influencing force transmission.
- -- Undercutting
- Material removal that causes loss of contact between the cam and follower.
- -- Motion Diagrams
- Graphical representations of follower motion enabling analysis of displacement, velocity, acceleration, and jerk.
