The cycle finishes the contour area from the contour starting point

to the contour end point. At the end of the cycle, the tool returns to

the starting point.

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 %).
