Project SLOPE 1 WP 4 – Multi-sensor model-based quality control of mountain forest production
Project SLOPE1
WP 4 – Multi-sensor model-based quality control of mountain forest production
Work Package 4: Multi-sensor model-based quality
control of mountain forest production
The goals of this WP are:• to develop an automated and real-time grading (optimization) system for the forest production, in order to improve log/biomass segregation and to help develop a more efficient supply chain of mountain forest products• to design software solutions for continuous update the pre-harvest inventory procedures in the mountain areas • to provide data to refine stand growth and yield models for long-term silvicultural management

Detailed procedure related to measurement of NIR along the whole harvesting scenario
Pile of logsThe cross section of logs stored in piles is easily accessible for direct measurement. Such measurements will be repeated periodically in order to monitor the quality depreciation and to determine the most optimal scanning frequency. The result of measuring NIR spectra of logs stored in piles will be NIR quality index #5
LaboratorySamples collected in the forest will be measured instantaneously after arrival in the laboratory (at the wet state and with rough surface) by using the bench equipment (NIR quality index #6). However, samples will be conditioned afterward and their surfaces prepared (smoothed) in order to eliminate/minimize effects of the moisture variations and light scatter due to excessive roughness on the evaluation results of fresh samples.
Protocol for NIR measurement of logs/wood
Procedure for logs:• turn on instruments• warm up detector• measure white reference• measure black reference• measure series of spectra• save results• post processing of spectra• in field data mining
(assuming availability of previously developed chemometric models)
Procedure for wood:• turn on instrument• warm up detector• perform instrument validation • PQ (Performance Qualification)• OQ (Operational Qualification)• measure background• measure series of spectra• save results• post-process the spectra• develop calibration models• perform calibration transfer (if required)
Important considerations
Logs:• Resolution (both spatial and spectral)• Measurement time• Number of measurements• Effect of ruggedness (effect of moisture, temperature and vibrations)
Wood:• Number of scanes per averaging• Number of measurements• Selection of scanning zones (wood section, early/late wood)• Effect of roughness and surface preparation• Effect of moisture• Effect of time (surface deactivation)

Conclusions
Many factors influence SW propagation in wood.
Parameters measured with the other NDT methods will be incorporated in the SW prediction models
Multiple linear regression analysis will be implemented for the definition of the importance of the different parameters (regression t-values) for the model.
The further development of Task 4.4 is based on the implementation of the lab scanner (i.e. purchase of sensors)
For the implementation of the methodology in the real case scenario, some practical issues(e.g. coupling-decoupling of sensors, etc.) have to be considered in combination with activity of Task 3.4

Task 4.5: cutting process quality indexcomparison of sensors
• a process where several cutting edges are involved in the cutting at the same time. The angle between the main cutting edge and fibre direction is ~0°, while the angle between feed direction and grain angle is ~90°.
• rather difficult to direct monitoring due to peculiarities related to the processing in the field/forest (suitable sensors, capability for acquisition of the proper energetic effects of cutting)
• relatively resistant to various sources of noise• great effect of the tool sharpness changing along the processing time• cutting speed and/or feed speed changes considerably between (and within) cutting cycles. • cutting power is related to the quantity of the material to split (log diameter) and variation
within the material itself:• reaction wood• knots• small ring width • decayed/rooted wood
Task 4.5: cutting process quality indexcross-cutting with the chain saw
Depends on:• wood density• cutting conditions• selected mechanical properties
of wood (such as fracture toughness, shear strength, MOE...)

Task 4.5: cutting process quality indexthe laboratory log cross-cut simulator
• one cutting edge is involved in the branch cutting-out. • the most demanding cutting configuration as the cutting forces foreseen in that arrangement are the
highest: the angle between the main cutting edge and fibre direction is ~90°, and between feed direction and grain angle is also ~90°.
• the cutting angle is very small• simpler to asses than of cross-cutting with a chain saw: due to the peculiar design of the processor head
where the cutting knife if fixed to the machine body and not any high-frequency changes to the process occurs
• depending on the processor design, the log may be moved against knives or alternatively the knives may be shifted along the trunk
• the fixed knifes system is relatively resistant for external sources of noise allowing measuring of the cutting power by means of various sensors
• an important issue to be considered is an effect of the tool geometry and sharpness• de-branching forces depend on:
• branch size• health state and moisture

Task 4.5: cutting process quality indexapplications for detection defects in logs
two quality indexes (numbers in the range from 0 to 1) associated to wood/log properties are determined:
• CP quality index #1: reflects the estimation of the “wood density” as related to the cutting resistance during cross-cutting of log by chain saw. The quality index #1 value is unique for the whole log.
CP quality index #1 = f(wood moisture content, tool wear, cutting speed, feed speed, log diameter, ellipsoid shape, presence of defects)
• CP quality index #2: reflects the “brancheness” of the log along its length and is estimated by means of signals associated with cutting out branches. The quality index #2 is spatially reolved.
CP quality index #2 = f(hydraulic pressure changes along the log length, changes of cutting forces in time, number of AE events or sound pressure level)
Task 4.5: cutting process quality indexalgorithms for data mining
• to plot a quality map – suport operator in taking decision - that is mostly affecting the whole following transformation chain!!!
• to grade the log• (to optimize cut-to-length)
Concept of the “quality map” indicating as a pattern sections of selected log properties, geometries and presence of various defects derived from the cutting-power analysis.
