# Industrial Specification: Blade Tensioning System

## 1. Technical Definition
A mechanical system designed to apply and maintain precise tension on oscillating blades to ensure optimal cutting performance and blade stability.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **150-450 N tension force, 0.1-0.3 mm blade deflection**. Failure boundary: **Tension force exceeds 550 N or drops below 100 N, blade deflection exceeds 0.5 mm**, Mechanism: **Hooke's Law elastic limit exceeded causing permanent deformation (yield strength &gt; 550 MPa), Hertzian contact stress &gt; 1.2 GPa causing surface fatigue**.

### 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.
