Prerequisites for standard NC blocks with radius compensation

The radius of the replacement tool must be the same as that of the
original tool. If the radii are not equal, the TNC displays an error
message and does not replace the tool.
Prerequisites for NC blocks with surface-normal vectors and 3-D
compensation
See “Three-Dimensional Tool Compensation (Software Option 2),”
page 218. The radius of the replacement tool can differ from the radius
of the original tool. The tool radius is not included in program blocks
transmitted from CAD systems. You can enter the delta value (DR)
either in the tool table or in the TOOL CALL block.
If DR is greater than zero, 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.
