Data interface device for transmitting tool data, manufacturing system and numerically controlled machine tool

A data interface device (2), comprising:

• a first interface module (21) configured to receive, from a tool data management device (1), tool data of a tool usable in numerically controlled machine tools;
• a second interface module (22) configured to be connected to a plurality of control devices (31a, 31b) of numerically controlled machine tools (3a, 3b) and to transmit tool data of tools usable in the numerically controlled machine tools (3a, 3b) to the control devices (31a, 31b) of the numerically controlled tool machine tools (3a, 3b);
• and
• a data processing unit (23) configured to receive tool data in a data format from the first interface module (21) and to convert the data format of the tool data received via the first interface module (21) into a target data format and to transmit tool data in the target data format to the second interface module (22), wherein the target data format is different than the data format of the tool data received via the first interface module (21) and is readable by a respective control device (31a;
• 31b) of the plurality of control devices (31a, 31b) which receives the tool data, such that the machine tool (3a;
• 3b), associated with said respective control device (31a;
• 31b) which receives the tool data, is controlled in accordance with the tool data received by the respective control device (31a;
• 31b).
