The position in the axes that form the machining plane areobtained from the retraction contour. The axis component perpendicular to this isdefined by DISCL. If DISCL=0, movement runs fully in the plane.– If only the axis is programmed perpendicular to the machining plane in the SAR block,the contour ends in P 1. The position of the other axes is obtained as describedpreviously. If the SAR block is also the deactivation block of the TRC, an additionalpath is inserted from P 1 to P 0, so that there is no movement at the end of the contourwhen the TRC is deactivated.– If only one axis on the machining plane is programmed, the missing 2nd axis ismodally added from its last position in the previous block.– For an SAR block without programmed geometry axis, the contour ends in P 2.
