Zusammenfassung:	The invention concerns a method for optimizing the veneer yield in veneer peeling. The contour of the log to be peeled is determined and the peeling axes at the ends of the log are determined by simulating the veneer yield. The desired veneer yield is determined at least as two veneer products having their own grades. These desired veneer products serve as basic values for the optimizing calculation. The maximum grade of the veneer yield is calculated, based on the dimensions and grades of the veneer products, as well as by iterating the places of the peeling axes and simulating the peeling process. When the peeling axes of the log ends giving the maximum grade yield have been found, the log is placed according to these peeling axes in the lathe and peeled into a veneer web to be cut with a clipper into said desired veneer products.
