Claim:
1. A numeric controller for controlling relative movement between a tool and a workpiece with a jig fixed to a machine tool, the numeric controller comprising: a three-dimensional model storage to store a three-dimensional model of at least one of the workpiece and the jig; a three-dimensional measuring unit to integrally measure shapes of the workpiece and the jig fixed to the machine tool and to generate measured data of the workpiece and the jig; a measured data storage to store the measured data generated by the three-dimensional measuring unit, wherein the workpiece and the jig are integrally recognized based on the measured data; and a shape processor to generate, based on the measured data of the workpiece and the jig stored in the measured data storage, an integrally-measured model in which the workpiece and the jig are integrally recognized, and further to generate an individually measured model of at least one of the workpiece and the jig in which the at least one of the workpiece and the jig is individually distinguished based on a comparison of the generated integrally-measured model and the three-dimensional model of the at least one of the workpiece and the jig stored in the three-dimensional model storage; wherein the numeric controller controls the relative movement between the tool and the workpiece with the jig by referencing the individually measured model generated by the shape processor.
