Chris, Peter's book is on google books: http://books.google.com/books?id=JNnQ8r5merMC&printsec=frontcover&dq=peter+smid+cnc+programming+handbook&hl=en&sa=X&ei=1UaRUcI3hcutAe2EgfAE&ved=0CDwQ6AEwAA
It's the CNC Programming Handbook, not CNC Fundamentals as earlier reported. Tool functions for lathes are described starting on page 103. The discussion on how geometry offsets are stored in the 10,000 + register values is discussed on page 388. More on this is in a different book by the same author (http://books.google.com/books?id=YKvH-zYd3VwC&pg=PA63&lpg=PA63&dq=wear+offset+geometry+offset+10,000&source=bl&ots=CPOMF8n2qL&sig=aOvNpnzxbrLUb8vMiwQlMZ3uwqc&hl=en&sa=X&ei=oUiRUfvpIIbmyQGr_YDwCA&ved=0CDUQ6AEwAQ#v=onepage&q=wear%20offset%20geometry%20offset%2010%2C000&f=false - page 63). >> To me this is a bit confusing. In a tool file I would think tool 1 >> basic info would be under tool 1,not tool 10001. I can more easily >> wrap my head around wear offsets under the 10001. I agree completely - it's confusing to me as well. It is totally natural to the machine operators trained on Fanuc that I have spoken with, however, which is why I stuck with it. If you're doing something to accommodate folks like Rick Lair who use this in a production environment, I would leave it as Fanuc handles it (e.g. G10 L1 P10012 sets the geometry offset, not the wear offset).
