METHOD FOR IMPLEMENTING LOG CUTTING IN A WAY OPTIMISING VENEER YIELD

摘要

The invention relates to a method and an apparatus for implementing log cutting in a way optimising veneer yield. In the method, a log (9) is measured by a measuring apparatus and measuring data are transferred to a computer to determine the contour of the log and to determine the cutting points of blocks such that it is possible to cut the log into blocks (2-8) having one or more different lengths. In the method, after having determined the contour of the log, fitting by means of the computer programmatically blocks of different sizes inside the log in a different order such that the total veneer yield of the log can be calculated and optimised considering obtainable full sheets and incomplete sheets of different grades and the demand of blocks of different lengths at the production facility and/or the price of sheets of different grades.
