17.2.5 Write online tool offset discretely
PUTFTOC
This command writes an offset value by means of a program command.
PUTFTOC(<value>, <length1_2_3>, <channel no.>, <spindle no.>)
Put Fine Tool Offset Compensation
The wear of the specified length (1, 2 or 3) is modified online by the programmed value.
Note
The online tool offset for a (geometric) grinding tool that is not active can be activated by
specifying the appropriate spindle number.
If the channel number is omitted, the online offset is effective in the same channel.
If the spindle number is omitted, the online offset is applied to the current tool.
17.2.6 Information about online offsets
Response in the case of tool change
● In cases where FTOCON has been active since the last tool or cutting edge change,
preprocessing stop with resynchronization is initiated in the control when a tool is
changed.
● 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.
