Secondary D offsets
Sometimes two different features created by the same tool cannot be held in tolerance. If it is a close
tolerance one feature may be held in tolerance while the other runs out of tolerance. This may be
controlled by creating both features using different D values and creating the features with cutter
compensation. An example would be two different counter bores created using the G13 function with just
the I value. If each G13 had its own D value the features in question could be controlled separately:
Feature 1 (G13 I.25 F10.Z-.5 D01),
Feature 2 (G13 I.3125 F10 Z-.25 D11)
