As a long time lathe operator and shop owner I hate to see the wheel re-invented. Operators are taught and used to T#### the first two digits are the tool number and the second two are the off-set number. I am not saying that your thoughts are not more flexible but it goes against 40 years of standard cnc lathe practice. Last two digits call Offsets from wear or adjustable off-set page with a column for X and a column for Z. I know you understand it but I cannot understand the need to go against convention. My oldest commercial control on the shop floor is a Cincinnati Milacron 900 1983 Version and it operates this way and my newest commercial control is a Fagor 8050 2006 Version and it too uses T####.
I also have three turning centers running LinuxCNC utilizing the tool patch. I would really to see this developed further with separate pages for fixed offsets (geometry) and assignable offsets (wear) as I have eight turning centers and to re-train operators how to run lathes does not appeal to me. Please explain to us lathe users why we have to move away from what has been a standard and works very well.

That's how I read it. And you can say "G43.2 H100" twice to make it 0.002" smaller.
