# Industrial Specification: Punch Tool

## 1. Technical Definition
A precision tool that creates holes or shapes in materials through hydraulic force.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **50-200 bar hydraulic pressure, 0.1-5.0 mm/s punch velocity, 0.01-0.05 mm positioning accuracy**. Failure boundary: **Hydraulic pressure exceeding 250 bar causes seal extrusion, punch velocity exceeding 10 mm/s induces material deformation, positioning error exceeding 0.1 mm creates dimensional inaccuracy**, Mechanism: **Seal failure occurs via extrusion at 250 bar due to elastomer yield strength (3-5 MPa), punch tip fracture results from Hertzian contact stress exceeding tool steel compressive strength (2000-2500 MPa), thermal fatigue cracking initiates at 300°C due to differential thermal expansion (α=11×10⁻⁶/°C for tool steel)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Hydraulic fluid contamination exceeding ISO 4406 18/16/13 cleanliness level | 8 | Spool valve sticking causing uncontrolled punch descent | Install 3 μm absolute filtration with differential pressure monitoring at 0.5 bar threshold |
| Tool steel tempering temperature drop below 200°C during heat treatment | 8 | Punch tip plastic deformation under 1500 MPa contact stress | Implement pyrometric control maintaining 550±10°C during tempering cycle |
