2.1. Key terms used in cam design

Try these first

1. 1.

   What is the base circle?

   Hint

   Think about the foundational shape of a circle in cam design.

2. 2.

   Define pressure angle.

   Hint

   Consider how forces interact at different angles.

3. 3.

   What does the base circle in cam design represent?

   • The largest circle in the design
   • The smallest circle defining the cam's profile
   • The pitch curve path

   Hint

   Think about the foundational shape.

4. 4.

   Is undercutting beneficial for cam performance?

   • True
   • False

   Hint

   Consider the effects of material removal.

5. 5.

   Design a cam profile that has a minimized pressure angle while ensuring efficient power transfer.

   Hint

   Think about adjusting the base and prime circles.

6. 6.

   Evaluate a given cam profile for potential undercutting. Suggest modifications to enhance follower contact.

   Hint

   Focus on the material interactions with follower shapes.
