Abstract
When the absolute value (|Tt−Tc|) of the difference between the turning time Tt of a log PW and the transport time Tc of the log PW is longer than a reference measurement time Ts, the turning-axis center line measurement time Tm is set to the absolute value (|Tt−Tc|) (Step S120), the rotation speed W of centering spindles 24a and 24b is set to a speed (Ws×Ts/Tm) lower than a reference rotation speed Ws, and also the measurement rotation angle α is set to an angle (αs×Ts/Tm) smaller than a reference measurement rotation angle as (Step S122). When the absolute value (|Tt−Tc|) is equal to or less than the reference measurement time Ts, the turning-axis center line measurement time Tm is set to the reference measurement time Ts (Step S116), the rotation speed W of the centering spindles 24a and 24b is set to the reference rotation speed Ws, and also the measurement rotation angle α is set to the reference measurement rotation angle αs (Step S118).
