Automatic resource assembly overview

Resource Manager uses coordinate systems to position components at the correct location when creating tool assemblies. These coordinate systems are defined in the part family templates in the Manufacturing Resource Library or imported from NX. When you create graphics for the part family template components, these coordinate systems are created and then saved to Teamcenter when you save the part file. When you add a component to an existing one, either manually or using the guided component search (GCS), Teamcenter checks the coordinate systems and aligns them according to preset rules.

You can see the correctly assembled tools in the Graphics view.

By default, Teamcenter uses two types of coordinate systems as specified in the DIN4003 tooling standard: the machine-side coordinate system (MCS) and the coordinate system workpiece-side (CSW). Each component has one MCS and any number of CSWs. If the component has multiple CSWs, they follow a naming scheme.

When Teamcenter builds the assembly, it always moves the component containing the CSW to the part containing the MCS. The transformation matrix of the component BOM line containing the CSW is updated whereby that of the component containing the MCS remains unchanged.

When you create a tool assembly, there are different methods to add components to build the assembly. You can use the Add Classified Component command, paste a component from the clipboard, or use the guided component search. The method available for you to use to add components depends on the object in the existing hierarchy that you select. The figure illustrates the different options available.

Tool component	Add Classified Component or Paste
Coordinate system
Connection point	Guided Component Search

Where in the tool assembly hierarchy the component is added is also affected by:

• Which object you select to add a component.

• Which method you use to add the component.

When adding a new component, Teamcenter determines where in the hierarchy to add the component.

Connection point	Coordinate system	Direction	Direction in the hierarchy
Plug	MCS	Machine-side	Up
Socket	CSW	Workpiece-side	Down

When joining the two components, Teamcenter joins a CSW to the MCS. If there are multiple possible CSWs, the user must determine which coordinate system to use.

If, for example, you have this assembly:

You want to add this new component:

If you select the CSW in the assembly and use the Add Classified Component command, Teamcenter searches for the MCS in the component to be added and adds it below the selected CSW in the hierarchy (the down direction).

If, however, you select the MCS in the assembly, Teamcenter finds three CSWs in the component to be added. You must select the correct coordinate system to use, and then Teamcenter adds the component above the component with the selected MCS (the up direction) in the assembly. In this example, the new component, C2 is added above C1.

If your company uses custom names for coordinate systems, your administrator can modify the coordinate system names in the following preferences:

• MRMPlugCSYSPrefixes

• MRMSocketCSYSPrefixes

• MRMNeutralCSYSPrefixes
