The cycle roughs the area described by the contour starting point,
contour end point
and plunge angle, taking the oversizes into
consideration.
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 %).
