Abstract
A relative displacement specification unit specifies a relative displacement between a jig and a tool. A position determination unit determines whether the jig and the tool are respectively positioned at a jig calibration point and a tool calibration point. A displacement correction unit corrects the measurement values of the displacements of the jig and the tool. A contact determination unit determines whether the tool has come into contact with a workpiece based on a measurement value related to a deflection of the tool. A tool length correction unit corrects tool length data based on the relative displacement when the tool is determined to have come into contact with the workpiece. A control unit generates a control command for controlling the jig or tool based on the relative displacement, a shape of the workpiece, and tool length data indicating a length of the tool.
