Machine shop tutorial?

[Kenneth Porter]

Is there a tutorial on how to enter instructions for machined and plated 
parts? In the homebrew MRP that I'm replacing, a plated part is made from 
an unplated machined part that might pass through several CNC machines, and 
is made from some quantity of a particular raw material. How would I build 
that up in OFBiz? (I figure that, given such a tutorial, I can enter some 
sample parts and then dump the system to XML see the structure. Then I can 
script up loading the rest of my parts and raw materials rapidly.)
