摘要： A cutting element includes a substrate that is axially symmetric about a central axis. The substrate has a radius perpendicular to the central axis and that extends from the central axis to an outer surface of the substrate. A super-hard material is coupled to the substrate, and the central axis passes through the super-hard material. The super-hard material has an external surface defining at least one ridge protruding from a remainder of the external surface. A central point on the central axis is offset from the external surface of the super-hard material by a distance equal to the radius of the substrate. A distance measured from the external surface of the super-hard material to the central point is greatest at a position between 25° and 45° from the central axis of the substrate.

摘要： A propelled milling machine includes a cutting rotor that receives power from an internal combustion engine via a rotor drivetrain. To adjust the speed of the cutting rotor, the rotor drivetrain includes a rotor drivetrain transmission operatively associated with a rotor drivetrain lubrication circuit. To regulate temperature of the lubricant, a heat exchanger circuit is associated with the rotor drivetrain lubrication circuit and includes a rotor drivetrain lubricant heat exchanger and a rotor drivetrain lubricant pump assembly. The quantity of lubricant directed to the heat exchanger is regulated based on one or more sensed operating parameters associated with the lubricant.

摘要： A machine for roadwork can include a frame, a power source, and a milling rotor that can be operatively connected to the power source and the frame. The machine for roadwork can also include at least one camera and an image processor. The at least one camera can be configured to capture one or more images of the milling rotor. The image processor can be in communication with the at least one camera. The image processor may be configured to analyze the one or more images of the milling rotor captured by the at least one camera. The image processor may also be configured to determine a scratch height of the milling rotor based on one or more images. The scratch height can define a height of the milling rotor on condition that the milling rotor is in contact with a surface of the roadway.

摘要： A system of differential working is provided wherein a controller of a construction machine is provided with a working depth data set and with a design surface data set. A location of the construction machine within a reference system external to the construction machine is determined, for example using a global navigation satellite system. The controller may determine the desired working depth at the current locations of the ends of the working implement from the working depth data set. The controller may determine the desired cross-slope at the current location of the working implement from the design surface data set. The desired working depths and the desired cross-slope may be communicated to a grade control system of the controller.

摘要： In one aspect, a method for monitoring a milling machine having a milling rotor and a rotor chamber surrounding the milling rotor includes propelling the milling machine in a direction of travel, positioning a door of the rotor chamber at a first position with an actuator, and receiving a signal indicative of a condition of the actuator for positioning the door of the rotor chamber. The method further includes determining that the door has encountered material based on the signal and opening the door of the chamber in response to determining that the door has encountered material.

摘要： A guidance system for a machine includes one or more guide assemblies. Each guide assembly includes a support member, a lever, an abutment device, a sensor, and a controller. The support member is fixedly coupled to a frame of the machine. The lever is angularly biased away with respect to the support member. The abutment device is coupled to the lever is configured to be abutted and guided on a structure extending along a direction in which the machine moves to modify a roadway surface. The sensor detects a measured angle between the lever and the support member when the abutment device is abutted against the structure. The controller controls an actuation of a steering actuator associated with one or more traction devices of the machine to turn the traction devices based on the measured angle to modify the roadway surface along an extent of the structure.
