Numerical Controller

摘要

A numeric controller is provided with a three-dimensional model storage which stores a three-dimensional model of at least one of a workpiece and a jig; a three-dimensional measuring unit which integrally measures shapes of the workpiece and the jig fixed to the machine tool; and a shape processor generating an integrally measured model based on the measured data, in which the workpiece and the jig being integrally recognized, measured by the three-dimensional measuring unit, and further generating, regarding at least one of the workpiece and the jig, an individually measured model in which the workpiece or the jig is individually measured based on the generated integrally measured model and the three-dimensional model of the workpiece or the jig.

1. A numeric controller for controlling relative movement between a tool and a workpiece with a jig fixed to a machine tool in accordance with numeric control information, the numeric controller comprising:
a three-dimensional model storage configured to store a three-dimensional model of at least one of the workpiece and the jig; a three-dimensional measuring unit configured to integrally measure shapes of the workpiece and the jig fixed to the machine tool and to generate measured data; a measured data storage configured to store the measured data generated by the three-dimensional measuring unit, wherein the workpiece and the jig are integrally recognized; and a shape processor configured 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 configured 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 the generated integrally measured model and the three-dimensional model of the at least one of the workpiece and the jig; wherein the numeric controller is configured to control relative movement between the tool and the workpiece with the jig by reference to the individually measured model generated by the shape processor.
