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 %).
