Abstract: A mobile milling machine can be equipped with a liquid spray system to introduce a liquid spray into a rotor enclosure to reduce the temperature of a plurality of cutting tools disposed on a rotatable cutting rotor. The liquid spray system can be associated with one or more surface wetness sensors to estimate the wetness of the work surface after the milling operation. The wetness of the work surface can be used to adjust the spray quantity of the liquid spray introduced by the liquid spray system.

Abstract: A milling machine can include a frame; an engine coupled to the frame; a cutting rotor coupled to the frame and driven by the engine, the cutting rotor configured to be lowered a selected distance into a surface; and a controller, the controller being configured to modulate a plunge velocity of the cutting rotor into the surface based on an engine load target or an engine speed.

Abstract: A milling machine includes a frame, a plurality of wheels or track members coupled to the frame, a moldboard movably coupled to the frame, a first rotor, and a second rotor. The first rotor is rotatably coupled to the frame. The second rotor is positioned to the rear of the first rotor and rotatably coupled to the moldboard.

Abstract: A system for sensing partial-cut-width in a cold planar machine comprises a frame, a cutting system mounted to the frame comprising a cutting tool extending across a cutting path, sensors positioned across the cutting path, and a controller electronically coupled to the sensors to determine a partial-cut-width of material for the cutting tool. A method comprises sensing depth distances across a cut width of a cutting tool, determining a difference in depth distances, determining a location for the difference in depth distances, determining a portion of the cut width based on the determined location to determine a partial-cut-width.

Abstract: An apparatus for actuating a vibratory mechanism in a vehicle comprising a sensor configured to produce an operational value signal indicative of an operational characteristic of the vehicle; a computing device operable to receive the operational value signal and determine actuation values based at least in part on the operational value signal and to produce a corresponding control signal for selectively actuating the vibratory mechanism; and an input device configured to modify the actuation values during operation of the vehicle. A method for controlling a vibratory mechanism in a vehicle comprising the steps of producing an operational value signal indicative of an operational characteristic of the vehicle; determining actuation values from the operational value signal; modifying actuation values during operation of the vehicle; and signaling the vibratory mechanism to actuate in response to actuation values.
