Combination die is the correct answer.

In progressive die, two or more operations can be performed only at the different stage or different stroke of the ram.

But in compound die the two or more cutting operations are performed at a single stage or single stroke of the ram.

Whereas in combination die the two or more cutting and non-cutting operations are performed at a single stage or a single stroke of the ram.

Combination die is the correct answer.

My opinion is C) combination die, because in this process two or more operation performed in a single stroke of the ram.

In a progressive die are performed simultaneously two or more operation at the single Stoke of the ram in different locations.

Washers made by progressive die.

In progressive die, two or more operations are performed but at different stations, Combination and compound die also perform more operations but at same locations.

The combination die performs two or more than two cutting and forming operations.

And the compound die performs two or more than two cutting operations at same stations.

The correct answer is: compound die.

A compound die is a type of die that performs two or more operations simultaneously at a single stroke of the ram. This means that multiple operations, such as:

- Cutting
- Punching
- Forming
- Bending
are performed in a single die, at the same station, and in a single stroke of the ram.

Compound dies are designed to:
- Increase productivity
- Reduce production time
- Improve accuracy
- Minimize material handling

Here's why the other options are incorrect:

- Simple die: Performs only one operation at a single station.
- Progressive die: Performs multiple operations at different stations, with the material moving from one station to the next between strokes of the ram.
- Combination die: Performs both cutting and non-cutting operations at the same station, but not necessarily simultaneously.

Compound dies are commonly used for high-volume production of complex parts, such as:

- Automotive components
- Aerospace parts
- Electronic hardware
- Medical devices.

Here they have mentioned two or more operations (means one is cutting and other is forming) here they also mentioned single stroke hence progressive die is not correct answer.

The correct answer is combination die.

I agree B is the right answer.
