W4: Grinding-specific tool offset and tool monitoring
18.2 Online tool offset
Cutting edge changes can be implemented without preprocessing stop.
Note
Tool changes can be executed in conjunction with the online tool offset through the selection
of T numbers.
Tool changes with M6 cannot be executed in conjunction with the online tool offset function.
Machining plane and transformation
● FTOCON can be used only in conjunction with the "Inclined axis" transformation.
● It is not possible to change transformations or planes (e.g. G17 to G18) when FTOCON is
active, except in the FTOCOF state.
Resets and operating mode changes
● When online offset is active, NC-Stop and program end with M2/M30 are delayed until the
amount of compensation has been traversed.
● The online tool offset is immediately deselected in response to NC-Reset.
● Online tool offsets can be activated in AUTOMATIC mode and when the program is active.
