# Industrial Specification: Grade and Slope Control

## 1. Technical Definition
A precision control system that regulates the grade (elevation) and slope (cross-slope) of the road surface during the recycling process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-5.0% grade, ±0.5% slope**. Failure boundary: **Grade control fails at 5.5% deviation, slope control fails at 0.75% cross-slope error**, Mechanism: **Hydraulic servo-valve stiction exceeding 0.02 N·m torque threshold causes position feedback loss**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Laser receiver misalignment exceeding 3 arc-minutes | 8 | Grade sensor drift accumulating 2 mm/min error | Dual-axis auto-calibration with 0.5 arc-minute resolution encoders |
| Hydraulic fluid contamination at ISO 4406 18/16/13 | 8 | Proportional valve spool seizure within 15 operating cycles | 5 μm absolute filtration with real-time particle counting |
