APPROACH OF DYNAMIC PRODUCTION SETTINGS FOR MACHINE STRENGTH GRADING

摘要

Objective of this paper is to present for machine strength grading a new method for determination of settings which combines the best parts of machine and output control methods, and is based on modern grading technology and utilisation of accumulated data. Key-element of the new method is continuous recording of the grading measurement data in computer and automated adjustment of the settings. Method is verified by using grading data and simulated strength values of 200 OOQ spruce timbers. Results show that this method works correctly also when the quality of incoming timber changes. As a result, the graded timber has less variable strength and fulfils the requirements. Economic benefit is obtained by higher yield to better grades.
