# Industrial Specification: Torch or Shear Cutting

## 1. Technical Definition
A metal cutting component that separates materials using either thermal energy (torch) or mechanical shearing force.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 MPa hydraulic pressure for shear, 0.3-1.5 MPa oxygen pressure for torch**. Failure boundary: **Shear blade yield strength exceeded at 550 MPa stress, torch nozzle thermal fatigue at 1200°C cyclic temperature**, Mechanism: **Shear: plastic deformation from exceeding material yield strength; Torch: thermal fatigue from repeated heating/cooling cycles causing microcracking**.

### 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 | Shear valve spool seizure causing uncontrolled cutting motion | Install 3 μm absolute filtration with differential pressure monitoring |
| Oxygen purity drop below 99.5% at torch inlet | 8 | Incomplete combustion causing slag adhesion and nozzle obstruction | Implement mass flow verification with 0.1% accuracy oxygen analyzer |

## 3. Key Technical Parameters

## 5. Engineering Risks & FAQ

- **Caution**: 

### Q: What are the main differences between torch and shear cutting methods?
**A**: Torch cutting uses thermal energy (typically plasma or oxy-fuel) to melt through metal, while shear cutting applies mechanical force with blades or dies to physically separate materials. Torch is better for thick or complex shapes; shear provides cleaner edges on thinner materials.

### Q: Which material is best for cutting blades in high-volume operations?
**A**: Tungsten carbide offers superior wear resistance for high-volume shear cutting, while high-speed tool steel provides better toughness for applications with potential impact or variable material thickness.

### Q: How do I maintain torch nozzles and shear blades for optimal performance?
**A**: Regularly inspect torch nozzles for wear and clogging, clean with appropriate solvents, and replace when orifice deformation occurs. Shear blades require periodic sharpening, proper alignment checks, and lubrication of moving parts to maintain cutting precision.
