# Industrial Specification: Material Feed System

## 1. Technical Definition
A mechanical system that precisely advances and positions upholstery materials during the sewing process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 m/min linear feed rate, 0.1-0.5 mm positioning accuracy**. Failure boundary: **Feed rate exceeds 3.0 m/min causing material slippage, positioning error exceeds 1.0 mm causing seam misalignment**, Mechanism: **Coulomb friction coefficient μ=0.3 between feed rollers and material surface, when tangential force exceeds μ×normal force (F_t&gt;0.3×F_n), slippage occurs; elastic deformation of material substrate exceeding 0.8% strain causes permanent dimensional changes**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.
