# Industrial Specification: Coil Feeding System

## 1. Technical Definition
A mechanical system that precisely uncoils, straightens, and feeds metal strip material into a progressive stamping press at controlled speeds and positions.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 m/s feed speed, 0.1-0.5 mm positioning accuracy, 0.5-2.5 MPa straightening pressure**. Failure boundary: **Feed speed exceeds 3.5 m/s causing strip whip, positioning error exceeds 1.0 mm causing die misalignment, straightening pressure exceeds 3.0 MPa causing permanent material deformation**, Mechanism: **Resonant vibration at feed speeds above 3.5 m/s (natural frequency 8-12 Hz), cumulative positioning error from backlash exceeding 0.15 mm in ball screw assemblies, plastic deformation onset at 0.2% strain rate in cold-rolled steel**.

### 2.1 Analytical Physics Model
Governed by the **Tractive Power & Resistance Model**:

> **Primary Equation**: $P = \frac{F \cdot v}{\eta}$  
> **Engineering Impact**: Ensures motor torque capacity exceeds operational inertia.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| F | Total Tractive Resistance | Engineering Constant |
| v | Belt Speed | Engineering Constant |
| \eta | Efficiency | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Backlash accumulation in feed roller gear train exceeding 0.2 mm | 8 | Progressive positioning drift causing strip misalignment | Preloaded double-nut ball screw assembly with 0.05 mm maximum backlash |
| Electromagnetic interference from press clutch exceeding 50 V/m at 100 kHz | 8 | Encoder signal corruption causing feed position loss | Shielded encoder cables with ferrite chokes and differential signal transmission |
