Machining operations are usually carried out on CNC-programmed, fully automated machine tools. These sorts of machines require high levels of investment, since the tools used are of high quality and are correspondingly expensive. The same applies to the machined workpieces. Reliable, safe operations with clear allocation of the components involved protect the investment and keep running costs within the planned limits.
At the beginning of the machining step, it should be ensured that the workpiece is being machined with the right tool and according to the planned work program. For this purpose, it is necessary to clearly and safely assign the tool, the workpiece carrier, the workpiece, and the machining process. The seamless identification of components helps to avoid waste and to achieve a high level of productivity.
The workpiece carriers and the tool heads are equipped with RFID tags. These are read out by RFID read/write heads at the machining station. The control panel checks the plausibility of the process using the RFID data. Since the workpieces are assigned to a specific workpiece carrier, the system detects whether the workpiece, the tool, and the planned machining process are compatible with each other. Correct assignment is guaranteed. Compact read/write heads, tags with a ferrite core, and the IDENTControl Compact control interface are available for the metal environment and the generally confined conditions.

Reliable identification using the RFID system enables both fully automated and safe operation of CNC machinery. The read heads designed for this application can be installed directly in the metal environment. Together with the ferritecore tags, they guarantee safe functioning even under harsh ambient conditions. RFID data can be used for asset management and predictive maintenance. The tag can store process-related data such as the tool operating time. Targeted regrinding or replacement of individual tools can be carried out as required. The IDENTControl control interface is as rugged as it is reliable and can be combined with all control panels. Numerous fieldbus interfaces are available for their connection.
