# Industrial Specification: Bowl

## 1. Technical Definition
The bowl-shaped container in a vibratory bowl feeder that holds and orients parts for feeding.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 m/s² vibration amplitude, 50-100 Hz frequency**. Failure boundary: **Exceeding 4.2 m/s² vibration amplitude or 120 Hz frequency causes structural resonance**, Mechanism: **Resonant frequency excitation beyond material yield strength (typically 250-350 MPa for stainless steel bowls) leads to fatigue cracking at stress concentration points**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Abrasive particle accumulation exceeding 0.5 mm layer thickness | 8 | Increased friction coefficient from 0.15 to &gt;0.35 causing part jamming | Integrated air knife system with 2-3 bar pressure for continuous debris removal |
| Thermal cycling between 20°C and 80°C at &gt;5 cycles/hour | 8 | Differential expansion creating &gt;0.1 mm gaps at bowl-track interface | Monolithic bowl-track construction with Invar alloy (CTE 1.2×10⁻⁶/°C) for dimensional stability |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |
| :--- | :--- | :--- | :--- |
| spec | Config-dependent | mm | Verified |

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

### Q: What materials are best for vibratory feeder bowls in harsh environments?
**A**: Stainless steel bowls offer superior corrosion resistance and durability for harsh or washdown environments, while aluminum provides lightweight strength for general applications.

### Q: How does the spiral track design affect part feeding efficiency?
**A**: The spiral track's pitch, width, and surface finish determine part orientation, feed rate, and separation - custom designs optimize for specific part geometries and production speeds.

### Q: Can vibratory feeder bowls be customized for different part sizes?
**A**: Yes, bowls can be custom-engineered with specific diameters, track configurations, and mounting flanges to accommodate various part dimensions and feeding requirements.
