Upon returning from the dressing interrupt, axis cycle or reciprocation
resumes as does program execution from the point of interruption.
Important: When dressing occurs, the in-process dresser feature generates
offsets based on the newly dressed wheel size. These offsets are activated
as necessary upon the wheel’s return to the calling program. For details on
the in-process dresser feature, see chapter 21.
