Jr,
Yes, I can see an advantage to your system also, but in my case; there is only one setup for the gage and I handle the "offset" say by doing a facing first in my Cam program. EG. If I face off .020, I simply start each new operation as necessary at -.020 and go on. (To be honest, if it is a drilling operation, I just let it cut air for that extra .020
