Cutting Tools Information Model overview – OPC UA for Cutting Tools

6 Cutting Tools Information Model overview

This section introduces the "OPC UA Information Model for Cutting Tools".

For the Cutting Tools use cases, subtypes of the information models Error! Reference source not found. and OPC 40210 are used for the machines and the implementation of the necessary objects are specified and necessary attributes are added.

The ToolManufacturingMachineType (subtype of 8:MachineToolType) is used for the implementation of the tool manufacturing machine, as shown in Figure 6 and the ToolMeasuringMachineType (subtype of 9:GMSType) is used for the measuring machine as shown in Figure 7.

For job management the 7:JobManagementType of OPC 40001-3 is used as inherited from Error! Reference source not found. version 1.02.

For data exchange, a standardized 0:FileSystem shall be used.

Result management as defined by OPC 40001-101 is used within the measuring machine to notify the tool manufacturing machine about finished measurements.

The files describing the cutting tools geometry are to be stored in 8:WorkMasters file directory. These files can be stored and retrieved on the machine using the methods of 0:FileDirectoryType defined by OPC 10000-20. These work masters shall be referenced within the 6:WorkMaster of the 7:JobOrderControl and in the structure of the 6:ISA95JobOrderAndStateDataType describing a job in the 6:JobOrderList.

Within the measuring machine, the measurement data of the completed workpieces shall be stored in the Results folder of the 0:FileSystem. To ensure that the processing machine and higher level systems find the appropriate data, reference shall be made to this in the 9:GMSResultManagementType under 5:Results.
