In a method for determining an area milled by at least one construction machine or at least one mining machine by means of a milling drum (2) by means of working a predetermined area in several milling trajectories by at least one machine (1), determining the length of the milling trajectories along which a milling operation has taken place by evaluating the continuous machine positions, adding up the previously milled partial areas taking into account the length of the milling trajectory and the installed width of the milling drum (2), wherein the partial area currently milled along the milling trajectory is checked, either continuously or subsequently, for overlapping or multiple overlapping with any previously milled partial areas, and any partial areas which overlap are deducted, as overlapping areas, from the added-up previously milled partial areas, the total added-up partial areas milled minus the total overlapping areas established give the milled area.

A machine for excavating rock includes a frame, a cutting device, and a boom. The cutting device includes a cutting disc having a cutting edge, and the cutting disc is rotatable about a cutting device axis. The boom supports the cutting device and includes a first end, a second end, and a boom axis substantially parallel to the cutting device axis. The boom further includes a first portion and a second portion. The first portion is coupled to the frame for rotation about a first pivot axis between a raised position and a lowered position. The second portion is coupled to the cutting device, and the second portion is pivotable about a second pivot axis between a raised position and a lowered position.

The invention relates to a milling machine, in particular a road milling machine, a stabiliser, a recycler or a surface miner, comprising a drive means which is configured such that the milling machine performs translatory and/or rotatory movements on the ground, and a working means which is configured such that the ground is machined. The invention also relates to a method for operating a milling machine of this type. The milling machine according to the invention has a control unit 15 to input drive parameters and work parameters. The control unit 15 is distinguished by a selection unit 15C to select an operating mode from a plurality of operating modes. The control and processing unit 20 has a memory 20A which stores at least one predetermined drive parameter which is assigned to the operating mode, and/or at least one predetermined work parameter which is assigned to the operating mode, for each operating mode of the plurality of operating modes. The control and processing unit 20 is configured such that at least one assembly 4, 5; 8, 10, 11, 12, 13, 17, 18, 19 of the drive means and working means is controlled subject to the at least one drive parameter or work parameter which is stored in the memory 20A for the operating mode selected using the selection unit 15C, such that the particular machine function is carried out. The milling machine further provides that at least one function which describes the dependence of a work parameter of one assembly on a drive parameter of another assembly is stored for each operating mode, the control and processing unit 20 being configured such that, based on this function, at least one assembly of the working means or drive means is controlled such that the particular machine function is carried out.
