Data system, data interface device, manufacturing system, and method for controlling machine tool

A data system for generating and transmitting job data to at least one numerically controlled machine tool, comprising:

• a data interface device, which in turn comprises an interface module for data transmission and a data processing module for data processing and data generation,
• a CAM system, which is configured for generating and providing NC programs for workpiece processing on a numerically controlled machine tool and is coupled to the data interface device by means of its interface module for data transmission, and
• a production control system, which is configured for generating and providing manufacturing data for a product to be manufactured and/or for products to be manufactured and is coupled to the data interface device by means of its interface module for data transmission, wherein
• the data interface device is configured, on the basis of an NC program dataset received from the CAM system and a manufacturing dataset received from the production control system, to generate a job dataset by means of the data processing module, which is readable by a numerically controlled machine tool, and to transmit said job dataset by means of the interface module to a numerically controlled machine tool coupled thereto, in particular to a control device of the machine tool.
