As an alternative to R, D can be used to program the maximum path
deviation in the target point in order to define the grinding of the corner
which is created between two G0/G1 blocks. The two blocks must also be
programmed in direct succession here, otherwise the D is ignored. In
contrast to the corner cut with R, no plane must be selected during the
grinding of corners, since a polynomial (G6), and not a circle, is inserted
between the two blocks. The interpolation takes place in the space.
The high rate speed programmed for F has a modal effect for G0. It does not
have any affect on the speed for G1, G2 or G3. The value from
MK_VBAHNMAX is preset.
The values programmed for E and L have a modal effect and do not have any
affect on the high rate speed, but rather only on G1, G2 and G3. However, the
resulting feed speed is only considered if a value not equal to zero was
programmed for L. The value programmed for E is also stored time
synchronously in P561 and can be used e.g. as the spindle speed.
The speed is limited in such a way that neither the max. path speed
(MK_VBAHNMAX) nor the max. axis speeds (MK_VMAX) are exceeded. The
acceleration and deceleration ramps on the path are limited in such a way
that the max. ramps (MK_BESCHL, MK_BREMS) of the participating axes are
not exceeded.
Route operation: All axes reach their target point independently from each
other. The following block is only executed when all axes have reached their
target point.
The high rate speed programmed for F has a modal effect for G0 and all
programmed axes. It does not have any affect on the speed for G1, G2 or G3.
The values from MK_VMAX are preset.
The speeds of the participating axes are limited to the respective max. axis
speeds (MK_VMAX) in the machine constants. The maximum values
(MK_BESCHL, MK_BREMS) configured in the machine constants are used as
the acceleration and deceleration ramps, if smaller values were not selected
with G201.
General: The preparatory function G00 has modal effect.
The end position of the axes can be programmed either in the reference
dimension system (G90) or in the incremental dimension system (G91),
under the addresses of the positioning axes.
The unit F is dependent on the axes which are programmed. If only linear
axes are involved, input units/min (default: mm/min) is programmed in F. If
only rotation axes are involved, 1/min is programmed in F. If both are
involved, the unit F is dependent on whether the guide axes are linear or
rotation axes (see G16).
