NX Taught feature process does not include tool axis vector

When a user teaches a custom feature and operation to the NX Feature-Based Machining rules, the tool axis is not defined.  The feature will be found in whatever orientation it lies on the part, but the tool axis is not being correlated to the 'normal' vector of the feature.  

Solution

In the machining_knowledge.xml file, the taught operation does set the tool axis to the desired "specify vector" option from the dialog:
 

 
However, teaching the operation does not record what that vector was exactly.  There is no automatic connection to the feature's CSYS.  This is as designed.  Thus, when the operation is generated, NX just defaults back to the +ZM failsafe vector.

The user has to manually edit the rules here and add a vector definition.  For example, you can use the vector components of the "depth" direction of the feature:
 
oper.Smart_Tool_Axis_Vector[1] = -mwf.X_ORIENTATION_D
oper.Smart_Tool_Axis_Vector[2] = -mwf.Y_ORIENTATION_D
oper.Smart_Tool_Axis_Vector[3] = -mwf.Z_ORIENTATION_D
