Maybe someone mentioned already but some guys set the compound at high angle & increment the DOC that way. Dimensionally this works but if your material and/or tooling doesn't like this 'creep up on it thou by thou' mode, then its of less value. Another option: I have my coated/steel inserts set up on different tool holders than my uncoated 'sharper' inserts for aluminum, so its easy to just plop on a that cutter with say 10 thou to go & do the finishing operation with that if it makes sense.
