Numerical control device

A numerical control device that analyzes a processing program and controls processing of a process object by a processing device based on a result of analysis of the processing program, the numerical control device comprising:

• an attached-tool-information storage unit that stores therein attached tool information including a tool that is currently attached to the processing device and a tool holder to which the tool is attached;
• a tool-use-information creating unit that creates, in controlling the processing device by using the processing program, tool-use-information including information about a past record of a tool that was used by the processing device and a tool holder to which the tool was attached;
• a tool-information comparing unit that compares, before controlling the processing device by using the processing program, the tool-use-information created by the tool-use-information creating unit with the attached tool information stored in the attached-tool-information storage unit, and extracts difference in the tool and the tool holder as differential information;
• and
• a setup-instruction creating unit that creates, when the tool-information comparing unit extracts the differential information, setup-instruction information for instructing a setup operation for attaching a tool to a tool holder of the processing device based on the differential information, and outputs the setup-instruction information to an external device.

• the processing program includes a symbol that is used for discriminating a program area in which the tool-use information is stored from a storage area in which the tool-use information is stored, and
• the tool-use-information creating unit updates, after the setup operation, the tool-use information stored in the processing program to tool-use information for controlling the processing device based on the attached tool information, and stores processing program added with updated tool-use information in the external storage device.
