Patent number: 10273803Abstract: 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.Type: GrantFiled: December 15, 2016Date of Patent: April 30, 2019Assignee: Caterpillar Global Mining Europe GmbHInventors: Carl Moberg, Brent Duppong, Frank Kühnemund, Oliver Kortmann, Carsten Butz, Matthew Palmer

Publication number: 20180298753Abstract: 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.Type: ApplicationFiled: April 18, 2017Publication date: October 18, 2018Applicant: Caterpillar Global Mining Europe GmbHInventors: Carl John Moberg, Oliver Kortmann, Thomas Temmann, Konstantin Halle, Bjoern-Andre Huehn, Carsten Butz, Frank Kühnemund

Patent number: 10094216Abstract: 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.Type: GrantFiled: July 22, 2016Date of Patent: October 9, 2018Assignee: Caterpillar Global Mining Europe GmbHInventors: Carl J. Moberg, Thomas Temmann, Frank Kuehnemund, Martin Teiner, Paul Kornev, Rene Bilsing, Brent Duppong, Brian D. Rockwood, Bjoern-Andre Huehn, Oliver Kortmann
