2. Cam Terminology

Try these first

1. 1.

   What is a base circle?

   Hint

   Think of it as a foundational circle in cam design.

2. 2.

   Define pitch curve.

   Hint

   Consider how the follower's movement follows this path.

3. 3.

   What is the smallest circle from the center of the cam to the profile called?

   • Base Circle
   • Pitch Curve
   • Prime Circle

   Hint

   It's the foundation circle.

4. 4.

   True or False: Undercutting can enhance cam performance.

   • True
   • False

   Hint

   Think about contact stability.

5. 5.

   Design a cam profile that ensures a smooth follower motion while avoiding undercutting. Describe the parameters you would use.

   Hint

   Think about the relationship between the profile's radius and the follower's motion.

6. 6.

   Discuss how modifying the pressure angle affects the efficiency of the cam system in high-speed applications.

   Hint

   Consider the trade-offs between speed and mechanical stress.
