1. List the feature differences between forged parts and casted parts.

2. Why is control of the volume of the blank important in closed-die forging?

3. Why are there so many types of forging machines available? Describe the capabilities and limitations of each.

4. What are the advantages and limitations of cogging operations? Should cogging be performed hot or cold? Explain.

5. By inspecting some forged products, such as hand tools, you will note that the lettering on them is raised rather than sunk. Offer an explanation as to why they are made that way.

6. What are the major differences between hot forging and cold forging processes?

7. What are the functions of flash in hot closed-die forging?

8. Describe the factors involved in precision forging?

9. In a simple disk closed-die forging as shown below, why draft angle is needed? Why internal draft angles are larger than external draft angles?
