Abstract
The present invention relates to a method for determining the starting point of rounding turning in the turning of veneer. For turning a log, the knife carriage of the lathe is withdrawn into a home position before starting the turning of a new log and, during the initial phase of turning, the knife carriage is driven from the home position forward into the starting position of rounding turning at a fast rate. During the initial turning phase, the intensity of knife carriage vibration is monitored and the thus obtained intensity value of knife carriage vibration is used in the determination of the initial position of the log rounding phase.
