6. Circular and Tangent Cams

Try these first

1. 1.

   What type of cam is characterized by arcs of circles?

   Hint

   Think about the shapes used in their design.

2. 2.

   What is one advantage of Circular Arc Cams?

   Hint

   Consider ease of production.

3. 3.

   What is a characteristic of Circular Arc Cams?

   • Complicated manufacturing
   • Built from arcs of circles
   • High-pressure angles

   Hint

   Think about the overall design structure of these cams.

4. 4.

   True or False: Tangent Cams have only curved profiles.

   • True
   • False

   Hint

   Recall the structural characteristics of Tangent Cams.

5. 5.

   Design a simple cam profile using both Circular Arc and Tangent methods, ensuring that pressure angles are kept below 15 degrees. Describe potential advantages of your design.

   Hint

   Think about geometry and how to combine both types effectively.

6. 6.

   Evaluate the consequences of using Tangent Cams in a high-speed engine application. What design considerations must be made?

   Hint

   Reflect on the implications of speed and geometry.
