METHOD FOR MILLING OFF TRAFFIC AREAS WITH A MILLING DRUM, AS WELL AS MILLING MACHINE FOR CARRYING OUT THE METHOD FOR MILLING OFF TRAFFIC AREAS

摘要

In the method for milling off traffic areas with a milling drum of a milling machine, the following steps are provided:obtaining and storing target profile data (x, y, Ft_(x,y)) of a desired target profile (8) of a surface of the traffic area (3) in target condition, wherein target values (Ft_(x,y)) for a locally desired milling depth (Ft), which are specified relative to the surface of the traffic area (2) to be worked, are assigned to position data (x, y) in an in particular stationary coordinate system independent of the milling machine (6),determining the current x, y position of the milling drum (4) in the coordinate system and detecting the milling depth (Ft′) of the milling drum (4) currently adjusted relative to the surface of the traffic area (2, 3),during the milling operation, controlling the milling depth (Ft) of the milling drum (4) as a function of the target value (Ft_(x,y)) for the locally desired milling depth (Ft) assigned to the current x, y position of the milling drum (4) and the currently detected milling depth (Ft′),updating the target profile data (x, y, Ft_(x,y)) in the current position (x, y) of the milling drum (4) on the worked traffic area (3) by the currently actually milled milling depth (Ft), andstoring the updated target profile data (x, y, Ft_(x,y)).
