A robot control device includes: a graphic primitive selection unit that selects graphic primitives having a tag indicating machining details from CAD data in a CAD device; a tool data extraction unit that extracts, from the database unit, information on a machining tool associated with the machining details indicated by the tag attached to the selected graphic primitives; and an operation planning unit that allows a robot to perform a machining operation according to the extracted information on the machining tool based on the selected graphic primitives.

A numerical control apparatus which enables a numerical control apparatus for a machine tool suitable for executing a particular machining program to selectively execute the machining program. The numerical control apparatus includes a storage that stores unique information; a receiving part that receives a machining program including incidental information; a determination part that checks the incidental information included in the machining program received by the receiving part with the unique information stored in the storage, and determines whether information matching the unique information is included in the incidental information; and a machine controller that executes the machining program received by the receiving part to control the machine tool only when it is determined that information matching the unique information is included in the incidental information.

This disclosure relates to systems and methods for automatically detecting three-dimensional shaping in a three-dimensional model of a sheet-metal part. Therein, data of a three-dimensional model of the sheet-metal part, which extends in a plane spanned by a first direction and a second direction, is detected, wherein the sheet-metal part comprises a bulge in a third direction which is different from the first and the second directions. Then, a horizontal cut is made through the bulge, as well as a vertical cut perpendicular to the plane spanned by the directions, so that closed cross-sectional contours of the bulge are formed. After a transformation, e.g., a Fourier transformation, of the cross-sectional contours, a tool that produces the bulge can be allocated to the Fourier coefficients.
