Haimer’s Industry 4.0 digital tool management system
Haimer’s latest example of I4.0 technology is the Haimer data analyzer and controller (DAC). This digital tool management system enables a consistent exchange of tool data and connects the entire tool room (including CAD/CAM and the machine tool) to a digital I4.0 system.
The DAC establishes the connection with a corporate network and manages the exchange of target and actual values (as well as other tool data) between the individual tool room stations. The complete tool – Haimer tool holders in combination with available RFID data carriers, QR, or data matrix codes (which can be read and evaluated by various systems via a scanner) – can be clearly identified.
Through the network connection, the DAC also provides additional tool data: assembly instructions, article numbers, stock adjustments, and 3D models. The DAC also supports the user in the analysis of production data and process optimization.
The DAC in action
In the CAD/CAM system, a tool assembly order is generated and sent to the DAC, which generates a tool ID which accompanies the tool throughout the entire process for traceability. The subsequent stations – assembly (e.g., shrinking), measuring and balancing – all communicate with the DAC.
After the last value transfer, the data is sent to the machine tool control, where the correct magazine location is specified. Potential confusion regarding the correct magazine location can be prevented by scanning the tool ID at the machine.
Depending on the unbalance tolerance, an adaptation (such as reduction) of the maximum spindle speed takes place, if necessary. After the milling operation, data on the remaining tool life is transferred back to the DAC.
No operator error
The system is easy to operate: The user controls the entire process by simply clicking and confirming (data transfer). Since no manual input is required (or even possible), there is no false input, and thus no collision risk. The Haimer DAC concept is scalable from small to large and makes digitization in tool management feasible for small and medium-sized companies as well as larger organizations. The customer can take over existing machines and systems, as these can also be integrated by the DAC.
