How Jidoka AI Transformed Dowel Pin Quality Control in High-Speed Wood Processing
In a PoC with a European wood processor, Jidoka’s AI-powered inspection achieved 99.8%
accuracy at 1,200 parts/min, detecting cracks, knots, burns, and grain flaws — marking a
breakthrough in wood and furniture component quality control.
OVERVIEW
Furniture manufacturing relies on wooden dowel pins
that demand both dimensional and visual quality checks.
While dimension sorting is often automated, visual
defects such as discolouration, cracks, or burn marks
typically require manual inspection. For a high-volume
European manufacturer, this dependency created
challenges: inspection was slow, labour-intensive,
and inconsistent. Given the unpredictable defect types,
irregular spacing, and high-speed movement, traditional
inspection methods were not viable.
THE OPPORTUNITY
The proof-of-concept addressed four core challenges in dowel pin quality control:
- Unpredictable defect types (cracks, knots, grain imperfections, burns)
- High SKU variation across dowel designs
- High throughput requirement (>1,000 parts/minute)
- Over-reliance on manual inspectors for visual quality
The approach
JIDOKA’S APPROACH
Jidoka integrated its Kompass AI visual inspection engine directly with the dowel pin cutting machine:
- High-Speed AI Detection: Trained on >10,000 images, the system achieved 99.8% accuracy — outperforming both manual inspection and traditional vision systems.
- Real-Time Integration: Image data was streamed from the machine camera to Jidoka’s AI, which returned defect decisions in under 50 milliseconds, enabling ejection at 1,200 parts/minute.
- Non-Intrusive Deployment: The solution was layered onto the existing machine setup without requiring process changes or extra equipment
