affected by

5.8 Programmable tool offset (TOFFL, TOFF, TOFFR)
Command for the compensation of the effective tool length
can be programmed with or without index:
TOFFL
• Without index:
TOFFL=
The programmed offset value is applied in the same direction
as the tool length component L1 stored in the compensation
memory.
• With index:
TOFFL[1]=
The programmed offset value is applied in the same direction
as the tool length component L1, L2 or L3 stored in the offset
memory.
The commands and
TOFFL
Note:
How these tool length offset values are calculated in the axes is
determined by the tool type and the current working plane
( / / ).
G17 G18 G19
Command for the compensation of the tool length in the
component parallel to the specified geometry axis
is applied in the direction of the tool length component,
TOFF
which is effective with non-rotated tool (orientable toolholder or
orientation transformation) parallel to the
specified in the index.
Note:
A frame does not influence the assignment of the programmed
values to the tool length components, i.e. the workpiece
coordinate system (WCS) is not used for the assignment of the
tool length components to the geometry axes, but the tool in the
basic tool position.
Identifier of the geometry axis
Command for the compensation of the effective tool radius
changes the effective tool radius with active tool radius
