Numerical control system coordinating with tool catalog database

A numerical control system comprising:

• a numerical controller having a tool database in which data of a tool to be used for machining is stored;
• and
• a tool catalog database which is accessible among a plurality of machines and which is accessible by the numerical controller,
• wherein the numerical controller is configured to:
• retrieve from the tool catalog database, at least one piece of tool catalog data including first cutting condition data;
• receive a modified first cutting condition data input from an operator into the tool database and receive first modified cutting condition data from a machining program;
• prioritizing extraction of the modified first condition data from the machining program, and extracting the modified first condition data from the machining program;
• control a machine to execute a machining based on the machining program and the modified first cutting condition data of the machining program, the modified first cutting condition data used for the machining;
• after execution of the machining, receive an instruction from the operator approving or denying an update to the tool catalogue database based on the modified first cutting condition data of the machine program, and
• in response to the instruction from the operator approving an update, update the first cutting condition data stored in the tool catalog database with the modified first cutting condition data of the machining program used for the machining, or update the first cutting condition data stored in the tool catalog database with the modified first cutting condition data of the machining program used for the machining and with modified cutting condition data in the tool database that is not included in the modified first cutting condition data of the machining program,
• wherein the updated first cutting condition data in the tool catalogue database is accessible by the plurality of machines.
