DAC System Connects Toolrooms by Exchanging Tool Data

Haimerc’s DAC (data analyzer and ontroller), a digital tool management system, consistently exchanges tool data and connects the toolroom (including CAD/CAM and the machine tool) to a digital Industry 4.0 system.

The DAC establishes the connection with a corporate network and manages the exchange of target and actual values between the individual toolroom stations. 

Through the network connection, the DAC also provides additional tool data: assembly instructions, article numbers, stock adjustments and 3D models. The toolalso analyzes production data and process optimization.

In the CAD/CAM system, a tool assembly order is generated and sent to the DAC, which generates a tool ID that accompanies the tool throughout the entire process for traceability. The subsequent stations—assembly (for example, 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. 

The user controls the entire process by clicking and confirming data transfers. Since no manual input is required, there is no risk of false input and collisions, Haimer says. The 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 user can take over existing machines and systems, which also can be integrated by the tool.
