# Industrial Specification: Progressive Die Set

## 1. Technical Definition
A precision tool assembly used in progressive stamping presses to perform multiple operations on metal strips in a single pass.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 mm punch-die clearance, 200-800 kN press force, 40-120 SPM stroke rate**. Failure boundary: **Punch-die clearance exceeds 3.0 mm causing material rollover, press force exceeds 1000 kN causing punch buckling, stroke rate exceeds 150 SPM causing thermal expansion mismatch**, Mechanism: **Excessive clearance causes Hertzian contact stress concentration exceeding 2500 MPa yield strength of D2 tool steel, buckling occurs when Euler critical load formula P_cr = (π²EI)/(KL)² is exceeded, thermal expansion mismatch occurs when ΔT &gt; 150°C creating differential expansion between punch (α=11.0×10⁻⁶/°C) and die (α=12.5×10⁻⁶/°C)**.

- **Caution**: 

### Q: What materials are typically used in progressive die sets for durability?
**A**: Progressive die sets are constructed from hardened tool steels like D2 or A2 for the main components, with carbide inserts for high-wear areas and hardened steel guide pins and bushings for precision alignment and longevity.

### Q: How does a progressive die set improve manufacturing efficiency?
**A**: A progressive die set performs multiple stamping operations (cutting, bending, forming) on a metal strip in a single pass through the press, significantly reducing production time, material handling, and increasing output consistency.

### Q: What are the key components of a standard progressive die set?
**A**: Key components include the die plate (stationary base), punch plate (holds moving punches), stripper plate (removes material from punches), and guide pins with bushings (ensure precise alignment between plates during operation).
