Press Tool Classifications — What Is a Compound Die? Choose the most accurate definition of a compound die used in presswork.

Introduction / Context:
Understanding die types enables efficient sheet-metal process planning. A compound die is specifically designed to carry out multiple cutting actions in a single station, enhancing productivity and positional accuracy between related cuts.

Given Data / Assumptions:

• Focus is on cutting actions such as blanking and piercing.
• All operations occur at one station during a single press stroke.
• No forming action is implied.

Concept / Approach:
In a compound die, two or more cutting operations are performed simultaneously at the same station. This differs from progressive dies (multiple stations along a strip feed) and combination dies (which mix cutting and forming in one station).

Step-by-Step Solution:
Identify that only cutting operations are intended.Confirm that the operations occur in a single station per stroke.This matches the definition of a compound die.Exclude progressive (multi-station) and combination (cut + form) definitions.

Verification / Alternative check:
Typical example: simultaneously blanking an outer profile and piercing holes in one stroke.

Why Other Options Are Wrong:
Single-operation die is a simple die.Multi-station actions define a progressive die, not compound.Cut + form in one station defines a combination die.

Common Pitfalls:
Mixing up “compound” with “combination” due to similar wording; remember compound = cutting-only, combination = cutting + forming.

Final Answer:
two or more cutting operations are performed at one station of the press in every stroke of the ram
