# Industrial Specification: Cutting Blade / Shear

## 1. Technical Definition
A sharp-edged component designed to cut or shear materials through hydraulic force application.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **150-350 bar hydraulic pressure, 0.1-2.5 m/s cutting velocity**. Failure boundary: **Material yield strength exceeded at 450 bar hydraulic pressure or 3.8 m/s cutting velocity**, Mechanism: **Fatigue crack propagation from cyclic stress concentration at blade edge radius below 0.05 mm, following Paris' Law with C=1.2e-11 and m=3.0 for tool steel**.

### 2.1 Analytical Physics Model
Governed by the **Goodman Cyclic Life Prediction**:

> **Primary Equation**: $\frac{\sigma_a}{S_e} + \frac{\sigma_m}{S_u} = 1$  
> **Engineering Impact**: Prevents catastrophic frame failure due to cyclic loading.

- **Caution**: 

### Q: What materials are best for cutting blades in heavy machinery applications?
**A**: For heavy machinery, high-carbon tool steel offers durability and edge retention, tungsten carbide provides extreme hardness for abrasive materials, and high-speed steel balances wear resistance with toughness for varied applications.

### Q: How do I maintain the cutting edge on industrial shear blades?
**A**: Regular inspection for wear, proper cleaning after use to prevent material buildup, and following manufacturer sharpening specifications help maintain optimal cutting performance and extend blade lifespan.

### Q: What factors should I consider when replacing a cutting blade in manufacturing equipment?
**A**: Consider material compatibility with what you're cutting, mounting interface specifications to ensure proper fit, hydraulic pressure requirements, and whether you need standard or custom blade dimensions for your machinery.
