することができなかった。(Problems to be Solved by the Invention) Incidentally, the actual maximum value of the bending of the saw blade does not always occur at the center position between the saw blade guide members. That is, if the maximum position of the bending amount is farther from the center position with respect to the bending amount detection device, the actual maximum value of the bending amount becomes larger than the predicted maximum value of the bending amount.
Conversely, if the maximum position of the bending amount is closer to the center position with respect to the bending amount detection device, the actual maximum value of the bending amount is smaller than the predicted maximum value of the bending amount. . As described above, the detection value of one bending amount detection device causes a measurement error, and it is not possible to accurately predict the maximum value of the bending amount.
