Abstract: An implement system for a machine includes a boom housing a drive mechanism for a cutting implement, and having a plurality of oil outlet ports formed therein. A control mechanism is configured to receive data indicative of an expected change in location of the outlet ports relative to an oil fill line within the boom, and vary a pattern of incoming oil flow to limit entrainment of air in the oil.

Abstract: A control system for controlling operation of a cutter motor and a cutter boom movement mechanism of a machine includes a sensor that measures an amount of load associated with the cutter motor. A controller determines whether the load on the cutter motor is different from a cutter motor load limit. If so, the controller is configured to adjust a velocity of the cutter boom movement mechanism relative to a tip velocity of a rotary cutting tool associated with the machine based on the difference between the measured cutter motor load and the cutter motor load limit until a torque error of the cutter motor reaches a particular value, for instance, zero. Moreover, the controller may also adjust a current speed of the cutter motor in driving the rotary cutting tool based on the adjusted velocity of the cutter boom movement mechanism.

Abstract: A milling depth compensation system for milling rock determines a target position of a machine, an initial position of the work surface, and a target pose of the machine based on the target position of the machine and the initial position of the work surface. An actual pose of the machine is determined and differences between the actual pose and the target pose are used to determine a dynamic milling path of a milling tool. The dynamic milling path includes movement of the milling tool along a first path, a second path, and a third path. Command signals are generated to move the milling tool along the dynamic milling path.

Abstract: A site positioning system for an underground machine includes a first prism coupled with the underground machine, a second prism operatively coupled with the underground machine, a primary total station, and a reference prism may be in communication with the primary total station. A positioning controller is configured to control, responsive to receiving a High Accuracy Machine Position mode, the primary total station to monitor the first prism and the second prism and transmit a first prism position and a second prism position, respectively, to the positioning controller; control, responsive to receiving a Low Accuracy Machine Position mode, the primary total station to monitor the first prism and transmit the first prism position to the positioning controller; determine, responsive to receiving a Reference Prism Measurement mode, whether a reference prism measurement has been completed, and present positioning information for the machine based on one or more of the prism positions.

Abstract: A machine for cutting material includes an undercarriage including propulsion device for propelling the machine and a cutter head disposed on a tool support and positioning assembly movably supported by the undercarriage to remove material from a cutting surface. The machine further includes a plurality of ground-engaging devices connected to the undercarriage that can be simultaneously raised and lowered with respect to a ground floor. Examples of ground-engaging devices include stabilizers for stabilizing the machine when milling or cutting material and a load shield that prevents material from scattering underneath the machine.

Abstract: A machine includes an undercarriage having propulsions devices such as continuous tracks and a cutter head disposed on a cutter boom that is slidably supported over the undercarriage. During operation, the cutter head is positioned proximate to the cutting surface and may be maneuvered through a predetermined set of operations to make a plurality of horizontal or vertical cuts while feeding the cutter head into the surface. Once the cutter boom is fully extended, the machine must be trammed to a new position using the continuous tracks to conduct the next predetermined set of operations. The machine may be configured to retract the cutter boom prior to tramming the machine to avoid damage to the cutter boom and/or cutting surface.
