Possible ways of programming the end point P
0
for retraction
The end position is always taken from the SAR block, no matter how many axes have been
programmed. We distinguish between the following situations:
1. No geometry axis is programmed in the SAR block.
In this case, the contour ends at point P
2
(or at point P
1
, if P
1
and P
2
coincide). The
position in the axes, which describe the machining plane, is determined by the retraction
contour (end point of the straight line or arc). The axis component perpendicular to this is
defined by DISCL. If, in this case, DISCL = 0, the movement takes place completely
within the plane.
2. Only the axis perpendicular to the machining plane is programmed in the SAR block.
In this case, the contour ends at point P
1
. The position of the two other axes is
determined in the same way as in 1.
