For an SAR block without programmed geometry axis,
the contour ends in P . The position in the axes that form the machining plane are
2
obtained from the retraction contour. The axis component perpendicular to this is
defined by DISCL. If DISCL=0, movement runs fully in the plane.
If in the SAR block only the axis perpendicular to the machining plane is programmed,
the contour will end at P
above. If the SAR block is also the TRC disable block, an additional path from P
is inserted such that no motion results at the end of the contour when disabling the
TRC.
If only one axis on the machining plane is programmed, the missing second axis is
modally added from its last position in the previous block.
For an SAR block without programmed geometry axis, the contour ends in P
position in the axes that form the machining plane are obtained from the retraction
contour. The axis component perpendicular to this is defined by DISCL. If DISCL=0,
movement runs fully in the plane.
