1. The magnetic field interacts with metal to generate heat in the metal which causes forming process.

2. Blanking is an operation in which the desired part is the sheet left out after making a punch hole in it.

3. In blanking operation, the clearance is provided on the die for obtaining the blank from metal sheet.

4. When material subjected to load then elongation becomes more faster beyond the yield point.

5. In which of the following operations is a dummy block used?

6. Forming dies are generally used in the blanking and piercing operations.

7. Progressive die is a die which can perform two or more operations in a single stroke.

8. In plastic deformation of metal, the metal strength decreases as the increase in its temperature.

9. The brittle material directly fractures without yielding when it reaches the ultimate strength material.

10. Which of the following is also called as forward hot extrusion?
