(A) The die

(B) Both the die and the punch equally

(C) The punch

(D) Neither the punch nor the die

In a blanking operation, the clearance is provided on the punch. When punching or blanking, a portion of the material from the larger piece or sheet metal strip is removed. When the small removed piece is discarded, the process is known as punching; however, when it is the useful portion, and the rest is trash, the process is known as blanking.

### Difference Between Punching and Blanking

The primary distinction between punching and blanking is that, in punching, the removed material is discarded while the final product is still present in the remaining material. In blanking, the final product is removed from the bigger metal sheet.

Punching and blanking are two ways to produce metal. Additionally, they perform well for making holes in a workpiece. In actuality, we can think of them as the two halves of a single process.

Die size equals blank size when using a blank. Since the blank in this instance is a useful part, it is corrected. Punch size = blank size – 2 x clearance.

Piercing/Punching operation: Punch size = blank size

Considering the Hole Size is a helpful component. When punching, clearance will be provided on the die.

Die size = blank size + 2 x clearance.

Summary:

## In a blanking operation, the clearance is provided on? (A) The die (B) Both the die and the punch equally (C) The punch (D) Neither the punch nor the die

The clearance is offered on the punch during a blanking operation. A portion of the material from the larger piece or sheet metal strip is removed when punching or blanking. The punch in the blanking process will have the clearance.
