Prerequisites for NC blocks with surface-normal vectors and
3-D compensation
The active radius (R + DR) of the replacement tool must not differ
from the radius of the original tool. You can enter the delta values
(DR) either in the tool table or in the TOOL CALL block. If there
are any deviations, the TNC displays an error message and does
not replace the tool. You can suppress this message with the
M function M107, and reactivate it with M108.See also: "Three-
dimensional tool compensation (software option 2)", page 423.
