TOOL_CORR_MODE_G43/G44
Processing of prog. length offsets G43/G44
Minimum input limit: 1
Protection level: 2/7
The machine data is only effective if MD EXTERN_CNC_LANGUAGE = 1.
When G43/G44 is active, it determines how length offsets programmed with H are pro- -ces-
sed.
0: mode A
The tool length H always acts on the Z axis,
independent of the current plane.
1: mode B
The tool length H acts on one of the three geometry axes
depending on the active plane:
G17 on the 3rd geometry axis (usually Z)
G18 on the 2nd geometry axis (usually Y)
G19 on the 1st geometry axis (usually X)
By multiple programming, length offsets can be established in all three geometrical axes in
this mode, i.e. by activating an offset, the existing length offset of another axis will not be
cancelled.
2: mode C
The tool length offset becomes valid in the axis programmed together with the
H code regardless of the selected plane. Further, the behaviour is as discribed
under mode B.
TOOL_CORR_MOVE_MODE
Traversing the tool length offset
Minimum input limit: - -
Protection level: 2/7
The machine data determines how the tool length offsets are applied.
FALSE: A tool length offset is only applied if the associated axis was programmed.
(Same behaviour as in previous SW versions)
TRUE: Tool length offsets are always applied, regardless of whether the associated
axes were programmed.
EXTERN_G0_LINEAR_MODE
Rapid traverse interpolation selection
Minimum input limit: 0
Protection level: 2/4
This MD determines G00 interpolation behaviour.
0: axes move like positioning axes
1: linear interpolation
