Road milling machine and method for measuring the milling depth
A method is provided for measuring the milling depth of a road milling machine, the machine being operative to mill a ground surface with a milling roller lowered to a milling depth to create a milling track, the machine including at least one side plate located to at least one side of the milling roller to engage an untreated ground surface, and the machine including a stripping plate operative to be lowered onto the milling track generated by the milling roller. The method includes measuring the milling depth of the milling track, the measuring including detecting a measurement value of a ground engaging sensor engaging the milling track.
1. A method for measuring the milling depth of a road milling machine, the machine being operative to mill a ground surface with a milling roller lowered to a milling depth to create a milling track, the machine including at least one side plate located to at least one side of the milling roller to engage an untreated ground surface, and the machine including a stripping plate operative to be lowered onto the milling track generated by the milling roller, the method comprising:
measuring the milling depth of the milling track, the measuring including detecting a measurement value of a ground engaging sensor engaging the milling track; and
correcting the measured milling depth in dependence on an offset distance between the ground engaging sensor engaging the milling track and a rotational axis of the milling roller, when the machine frame does not extend parallel to the untreated ground surface.
2. The method of claim 1 , wherein:
the measuring step further includes detecting another measurement value of another ground engaging sensor engaging the untreated ground surface, and wherein both measurement values are detected in relation to a machine frame of the road milling machine.
3. The method of claim 1 , wherein:
the measuring step further includes detecting the measurement value of the ground engaging sensor engaging the milling track in relation to another ground engaging sensor engaging the untreated ground surface.
