Manually extend the Classification hierarchy with a new class

If you extend your Teamcenter Classification hierarchy with new tool assembly classes, these must be reflected in the NX Library dialogs so that you can search in the new classes from within NX. Because NX supports only a limited number of tool types, you must map every new tool assembly in Teamcenter to a tool type in NX.

You can extend the hierarchy manually, or you can use the mrm_export_resources utility to perform these steps automatically.

The following steps show how to manually create a new class, Custom_Mill_Tool, to hold 5-parameter milling tools. The new class ID is TA_MILL_10_75.

Procedure

1. Create a new class in the Classification Admin application. Keep in mind that the NX Library mechanism only reflects tool assemblies found in the Resource Management→Tools→Assemblies branch of the classification hierarchy. For the example, you must create the Custom_Mill_Tool class within Resource Management→Tools→Assemblies→Milling.

2. Add all necessary class attributes. Every tool type within NX requires its own minimum set of attributes. These are based on the attributes that appear in the tool dialogs within NX CAM. For more information about the mandatory parameters necessary for a five parameter milling tool, see CAM Library→Cutter, tool holder, and device libraries→Creating new classes and subclasses→Attributes for new tool classes and subclasses in the Manufacturing General Help in the NX Help collection.

   Note Negative attribute numbers are reserved for Siemens Digital Industries Software attributes. If you add custom attributes, use positive attribute IDs.

3. Open the MACH\resource\library\tool\inclass\dbc_mrl_tooling_library_tlas_en.def file in an editor. You can find this file in the directory where NX is installed.

4. Add the new class to the class hierarchy section of this file as explained in Library class hierarchies in the NX Library Help.

5. If you assigned customer-specific attributes that are required by the NX CAM tools, adjust the event handler file to map to these attributes in the DBC retrieve procedure in the dbc_mrl_tooling_library_tlas_en.tcl file.

6. Restart NX and Teamcenter. The new class now appears in the NX Library dialog boxes when you search for a tool in NX.
