Adaptive seetings for machine strength grading

At present, the machine controlled grading procedures are based on predetermined static machine settings. The grading practice shows that the shifts in material properties happen and have an important influence on the properties of graded material. A new adaptive method which combines machine and output control approaches is presented here. The key element of this method is the utilization of continuously recorded grading measurement data for the automated adjustment of the settings. The method is verified by using grading data of almost 200 000 spruce boards.
