Timber grading (depends on timber
value and requirements of end user)
Volume estimation
Quality assessment (visual system in
forest, sensors in sawmill)

4. Quality grading – UNI ENV 1927-1

- Very simple for easier integration of sensors
- Light and flexible
- Possibility to measure delimbing forces

6. Concept of Intelligent processor
Processor head
 NIR
 Hyperspectral
 RFID
 Stress wave
 Branch index
 Cutting forces
• Interact with
database and ERP
• Measure loads and
volumes
• Full traceability
• Receive (cutting)
instructions
• Real time
connectivity
• Quality assessment
per single log (knots,
chemical and
physical
characteristics)

7. RFID marking of logs:
- Association of quality index to each item
- Full traceability of timber products
