Today when I was catching up on some reading on the LCNC mail list I saw mention of a standard for tool table data. Some where on here I remember reading about thoughts for how to lay out the tool table. Apparently there is a standard for this i don't know how widely adopted this is but it may be worth looking into if some one has access for ideas if nothing else. It is mentioned in wikipedia.org but there is not that much info there. ISO 13399 (Cutting tool data representation and exchange) thought I would share as it may be interesting for some one.
