# Industrial Specification: Automated Grading and Portioning Unit

## 1. Technical Definition
Automated unit for sorting fish by quality/size and cutting into standardized portions

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 m/s conveyor speed, 0-40°C ambient temperature, 85-110 kPa compressed air pressure**. Failure boundary: **Conveyor speed exceeds 2.5 m/s causing fish misalignment, ambient temperature exceeds 45°C causing sensor drift &gt;3mm, compressed air pressure drops below 70 kPa causing actuator stall**, Mechanism: **Bernoulli principle causing fish lift/misalignment at high conveyor speeds, thermal expansion coefficient mismatch (aluminum frame vs steel guides) causing dimensional instability, Boyle's law pressure-volume relationship causing insufficient actuator force**.

### 2.1 Analytical Physics Model
Governed by the **Tractive Power & Resistance Model**:

> **Primary Equation**: $P = \frac{F \cdot v}{\eta}$  
> **Engineering Impact**: Ensures motor torque capacity exceeds operational inertia.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| F | Total Tractive Resistance | Engineering Constant |
| v | Belt Speed | Engineering Constant |
| \eta | Efficiency | Engineering Constant |

### 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 | Proportional valve spool sticking causing portion weight deviation &gt;15% | Install 3μm absolute filtration with differential pressure monitoring at 150 kPa |
| Encoder signal loss for &gt;100ms due to EMI from 400V VFD switching at 8kHz | 8 | Servo axis overshoot causing blade collision with conveyor at 1.2m/s | Shielded twisted pair cabling with ferrite cores at both ends, ground plane separation of 50mm |

- **Caution**: 

### Q: What materials are used in the construction of this automated grading and portioning unit?
**A**: The unit is constructed with food-grade stainless steel for durability and hygiene, food-safe plastics for non-contact components, and high-carbon steel blades for precise, long-lasting cutting performance.

### Q: How does the unit ensure consistent portion sizes?
**A**: The unit uses a combination of an inspection sensor array to measure fish dimensions and a precision cutting assembly with high-carbon steel blades to cut fish into standardized portions according to pre-set parameters in the control system.

### Q: What are the main components included in this automated grading system?
**A**: The system includes four key components: a control system for operation management, a cutting assembly for portioning, an inspection sensor array for quality/size assessment, and a sorting mechanism to categorize fish based on grading results.
