That's OK, if you have a UG, you certainly have everything you need to manage the workshop, you do not need Excel setup sheets, but stil it is handy for the operator to have a list of tools with all descriptions. (Drill 842 does not tell everything about what it is). This CNC Scan is an option.
I worked (not any more) in a company programming machining centers and the most important task was having tools under control so that the operator did not have to change the ATC between jobs and the machine could run unmanned over night. In this case we had to group machining parts so that they could be machined with the tools in the ATC. The opeator set the machine (with the pallet pool) and the ATC before night and the machine run unmanned. That's why I believe a good tool database is so important. But every machine shop has its own ways how to manage the life, and the production.
Still there are many small workshops not having a CAM system, conversational programming is quite good on some machines (Mazaks, Heidenhan as an example). This is just from my experience.
<I>who makes them manually, ha ha ha</I> ;-)
