# Industrial Specification: Ram / Press Frame

## 1. Technical Definition
The structural frame and ram assembly that provides the force and guidance for bullet seating and crimping operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-75 kN ram force, 0.01-0.05 mm ram guidance clearance, 20-80°C operating temperature**. Failure boundary: **Ram force exceeds 85 kN causing frame yield stress &gt; 250 MPa, guidance clearance exceeds 0.08 mm causing &gt;0.1° angular misalignment, temperature exceeds 100°C causing thermal expansion &gt;0.15 mm**, Mechanism: **Frame yielding occurs when von Mises stress exceeds A36 steel yield strength (250 MPa) due to force concentration at stress risers. Guidance failure results from Hertzian contact stress exceeding 1500 MPa at bearing surfaces when misalignment exceeds elastic deformation limits. Thermal failure occurs when differential expansion between frame (α=12×10⁻⁶/°C) and ram (α=11×10⁻⁶/°C) creates &gt;50 MPa thermal stress at constraints.**.

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in the ram and press frame construction?
**A**: The frame is constructed from durable cast iron for stability, while the ram assembly uses high-strength steel alloy to withstand repeated force during bullet seating and crimping operations.

### Q: How does the ram and press frame assembly provide guidance during operation?
**A**: The precision-engineered frame uprights and ram components work together to ensure straight-line force application, maintaining consistent bullet seating depth and crimp quality throughout production cycles.

### Q: What are the main components in the BOM for this assembly?
**A**: The bill of materials includes three key components: the Frame Base for stability, Frame Uprights for structural support and guidance, and the Ram that delivers the necessary force for bullet seating and crimping operations.
