Abstract: A machine tool includes a bed supported on a ground by supporting jigs, a table movable in an X-axis direction, a spindle head movable in a Y-axis direction, a quill provided to be movable in a Z-axis direction, a spindle supported by the quill to be rotatable about its axis, feed mechanisms for moving the table and the like in the axis directions, and a numerical controller controlling operation of the feed mechanisms, and the numerical controller is configured to calculate motion errors based on load values acting on the supporting jigs by a motion locus estimator, an influence coefficient storage, a motion error calculator, and a motion locus storage, generate a correction signal for compensating for the motion errors by a position corrector, and add the generated correction signals to a position control signal transmitted from a position generator to a position controller.

Abstract: A reinstalling method which, when reinstalling an object to be supported, precisely restores the object to an initial installing state in a short period of time without requiring special skills. In a state before supporting of an object to be supported by support tools is released and in each of states in which the supporting is sequentially released, load acting on at least one support tool selected from among the support tools being in a supporting state is obtained. When reinstalling, the object is sequentially supported at the same positions as those before the release by the support tools in the reverse order to that of the release, and, a vertical-direction supporting position of each support tool is adjusted so that a load cell of the selected support tool detects the same value as the load obtained in the supporting state before the support tool was released.

Abstract: A workpiece fixing jig 1 includes a base 2 to be fixed on a table, and a clamping mechanism 10 provided on the base 2 for clamping a workpiece. The clamping mechanism 10 includes a first clamping portion 20 and a second clamping portion 30 provided to face each other. At least one of the first and second clamping portions 20 and 30 is configured to move forward and backward with respect to the other along a moving direction and the moving direction is set to a direction intersecting a direction in which the base 2 is fixed on the table. In using this workpiece fixing jig 1, the base 2 is fixed on the table after the workpiece is clamped between the first clamping portion 20 and the second clamping portion 30.
