The cycle finishes the contour area from the contour starting point
to the contour end point. When the cycle is completed, the tool
remains at the cycle end position.
 The tool plunges with the maximum possible angle,
leaving material remaining.
 The steeper the tool plunges into the material, the
greater the feed rate decrease (max. 50 %).
