# Industrial Specification: Bed / Die

## 1. Technical Definition
The stationary lower component of a hydraulic press brake that supports the die and provides a stable foundation for bending operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-1000 MPa compressive stress, 20-150°C operating temperature**. Failure boundary: **Yield strength exceeded at 1200 MPa compressive stress, fatigue failure at 10^7 cycles under 800 MPa alternating stress**, Mechanism: **Plastic deformation from exceeding yield strength (σ_y = 1200 MPa for hardened tool steel), fatigue crack propagation from cyclic bending loads following Paris' law (da/dN = C(ΔK)^m)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Misalignment exceeding 0.1 mm/m between bed and ram parallelism | 8 | Uneven die wear causing inconsistent bend angles exceeding ±0.5° tolerance | Laser alignment system with 0.01 mm/m precision and automatic hydraulic leveling compensation |
| Localized compressive stress concentration exceeding 1500 MPa at die corner radii | 8 | Micro-crack initiation and propagation leading to catastrophic fracture during 90° bending operations | Finite element analysis-optimized die profiles with minimum 6× material thickness corner radii and compressive residual stress treatment |

## 3. Key Technical Parameters

- **Caution**: 

### Q: What is the primary function of a press brake bed?
**A**: The press brake bed serves as the stationary lower component that supports the die and provides a stable, rigid foundation for precise metal bending operations in hydraulic press brakes.

### Q: Why are T-slots included in press brake bed design?
**A**: T-slots allow for flexible die mounting and positioning, enabling operators to secure various die types and adjust setups quickly for different bending applications while maintaining stability.

### Q: How does material choice affect press brake bed performance?
**A**: Cast iron provides excellent vibration damping and stability, while steel alloy offers higher strength-to-weight ratios. Both materials ensure minimal deflection during high-tonnage bending operations.
