# Model Card for Маломерное алюминиевое судно (Лазерная резка)

<!-- Provide a quick summary of what the model is/does. -->
This modelcard describes a **parametric DXF template** for laser-cutting aluminum sheets (3 mm, 5083-H116) to produce hull panels and structural elements of a small aluminum boat (4.5 m length). The output is a flat layout ready for CNC laser cutting with full dimensions, annotations, and cutting parameters.

## Model Details

### Model Description

<!-- Provide a longer summary of what this model is. -->
This is a **CAD-based flat pattern generator** for marine aluminum hull components. It includes:
- Hull side panels (port/starboard)
- Bottom panel
- Transom plate
- Longitudinal stringers (4×)
- Transverse frames (5×)
- Assembly marks & bend lines
All geometry is parameterized and exported as **DXF** with layers: `CONTOUR`, `BEND`, `HOLES`, `MARKS`.

## Uses

<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->

### Direct Use

<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->
- **Primary Use:** Generate flat patterns for laser cutting 3 mm aluminum sheets on CNC machines (fiber laser, 4 kW).
- **Users:** Boat builders, DIY marine fabricators, small shipyards.
- **Input:** Boat length, beam, deadrise angle, sheet size.
- **Output:** DXF file with nested parts, cut path, kerf compensation (0.25 mm), lead-in/lead-out.

---

### Out-of-Scope Use

- Not for structural certification (use with FEA validation).
- Not for thicknesses > 6 mm or materials other than 5xxx aluminum.
- Not for curved 3D forming (flat patterns only).

---

## Bias, Risks, and Limitations

<!-- This section is meant to convey both technical and sociotechnical limitations. -->
- **Kerf variation:** Actual kerf depends on laser focus, gas pressure, and material batch.
- **Thermal distortion:** Long cuts may cause minor warping in thin sheets.
- **Tolerance:** ±0.3 mm (achievable); tighter requires post-processing.
- **Safety:** High-power laser — requires proper shielding, ventilation, and trained operator.

---

## Recommendations

- Validate first cut on scrap material.
- Use nitrogen assist gas (16 bar) to prevent oxidation.
- Apply anti-spatter coating on nozzle.
- Nest parts to minimize sheet waste (< 15 %).
