ool data
Prerequisites for standard NC blocks with radius compensation
RR, RL
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.
On NC programs without radius compensation the TNC does not
check the tool radius of the replacement tool during the change.
Prerequisites for NC blocks with surface-normal vectors and 3-D
compensation
See "Three-dimensional tool compensation (software option 2)", page
528. 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 CAM 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.
