1
Calculates the areas to be machined and the cutting
segmentation.
2 Approaches workpiece for first pass from starting point, taking
the safety clearance into account (first in X direction, then in Z).
3 Moves at feed rate to target point X.
4 Depending on H:
 H=0: Machines the contour outline
 H=1 or 2: Retracts at 45°
5 Returns at rapid traverse and approaches for next pass.
6 Repeats 3 to 5 until target point Z has been reached.
7 If required, repeats 2 to 6 until all areas have been machined.
8 If H=1: Smoothes the contour
9 Retracts as programmed in Q.
