Press tool design — die type with simultaneous multiple operations In sheet-metal work, which die performs two or more operations simultaneously during a single stroke of the press ram at a single station?

Introduction / Context:
Press tools are tailored to productivity targets and part geometry. Understanding when operations occur in one station versus several stations helps select the correct die type and estimate cycle time, accuracy, and tooling cost.

Given Data / Assumptions:

• We compare common die types: simple, progressive, compound, and combination.
• “Simultaneously” and “single stroke” imply actions at the same press closure.
• “Single station” excludes sequential station-to-station progression.

Concept / Approach:
A compound die performs two or more cutting operations (e.g., blanking and piercing) in one press stroke at a single station. A progressive die performs operations at successive stations with the strip advancing each stroke. A combination die performs both cutting and forming in one stroke, but the key textbook definition for “simultaneous multiple operations at one station” points to the compound die.

Step-by-Step Solution:
Identify the requirement: multiple operations at one station in one stroke.Match to die type: compound die fits this exactly (e.g., pierce + blank together).Confirm that progressive dies need multiple stations and feeding between strokes.

Verification / Alternative check:
Standard manufacturing texts illustrate compound dies with concentric punch/die sets performing piercing and blanking simultaneously.

Why Other Options Are Wrong:

• Simple die: only one operation per stroke.
• Progressive die: multiple stations, not a single station.
• Combination die: mixes cutting and forming, but the classic definition sought here is “compound”.
• Transfer die: part is transferred between separate dies, not simultaneous at one station.

Common Pitfalls:
Mixing up “compound” and “combination”; the former is multi-cutting at one station, the latter blends cutting and forming.

Final Answer:
compound die
