摘要： A control system may be provided for operating a machine having a rotary cutting head. The control system may include a wrist capable of rotating about a wrist axis, a gear mechanism capable of driving rotation of the wrist. A cutting head may be attached to the wrist and capable of rotating about a cutter axis that is substantially perpendicular to the wrist axis. The control system may also include primary and redundant angular sensors capable of generating signals indicative of angular orientations of the wrist. The control system may additionally include a controller, capable of controlling operation of the wrist and the cutting head, comparing an actual angular orientation of the wrist to a target angular orientation, as indicated by the primary and secondary signals, and selectively inhibiting the cutting head from operating when the actual angular orientation differs from the target angular orientation by an operation threshold.

摘要： A cutting device for a cutting head includes a disc, a plurality of cutting elements secured to the disc, and a plurality of wear elements secured to the disc. The disc rotates about an axis of rotation, and the disc includes a peripheral edge. The cutting elements are spaced apart from one another along the peripheral edge of the disc. The wear elements are spaced apart from one another and from the cutting elements.

摘要： A cutter head includes a first member, a cutting bit, and a second member. The first member includes a first end and a second end and includes a first mass. The cutting bit is coupled to the first member proximate the second end. The cutting bit includes a cutting edge rotatable about the axis. The second member is rotatable about the axis and includes a second mass eccentrically positioned with respect to the axis. Rotation of the second mass causes the first member and the cutting bit to oscillate.

摘要： Methods and systems for automatically operating a continuous mining machine. One method includes performing an automated cutting operation without requiring manual interaction using a cutterhead included in an arm pivotably coupled to a movable platform and stopping the automated cutting operation without requiring manual interaction. Stopping the cutting operation includes (i) stopping at least one motor driving the cutterhead, (ii) operating a first actuator to retract the platform from a cutting face by a predetermined distance, and (iii) operating a second actuator to swing the arm to a predetermined tramming position.

摘要： In a tunnel driving apparatus, and particularly such apparatus where a work face is supported by fluid, a cutting appliance is employed which is composed of a swinging arm carrying a cutter head. The arm can range over the face to detach material therefrom with the cutter head. Means for driving the cutter head is accommodated entirely within the arm itself and a conduit or the like extends through the arm and serves optionally to remove debris by suction or to convey pressure fluid to the face to assist the cutter head.
