WORKPIECE MATERIAL CURVATURE DETECTING DEVICE， WORKPIECE MATERIAL MOVEMENT DEVICE， CONTROL DEVICE OF WORKPIECE MATERIAL MOVEMENT DEVICE， AND WORKPIECE MATERIAL MOVEMENT PROGRAM

PROBLEM TO BE SOLVED: To provide a workpiece material curvature detecting device capable of easily detecting the state of curvature and perform machining according to the state of curvature， a workpiece material movement device， a control device of workpiece material movement device， and a workpiece material movement program. SOLUTION: The workpiece material curvature detecting device is configured so that a lower left support portion 31L and a lower right support portion 31R of a first support portion 30a and a second support portion 30b， which are capable of supporting a lower side at both ends of a processed material 100 can be moved at least in the vertical direction by drive mechanisms 34a and 34b. After the operation， the first support portion 30a and the second support portion 30b stop， and the processed material 100 is set in the measurement state supported by the lower left support portion 31L and the lower right support portion 31R， a position detection device S1 detects a deviation in the position of side surfaces 100L， 100R of the processed material 100 with respect to the ideal shape.
