  • Publication number: 20230259129
    Abstract: An acquisition processing unit acquires position information of a work vehicle traveling in a predetermined area in response to a traveling operation by an operator. A recording processing unit records the position information, as a traveling trajectory of the work vehicle, and temporarily stops recording processing of recording the position information, in a case where the work vehicle is brought to a state in which the position information cannot be acquired during traveling. A notification processing unit notifies the operator of information indicating that the recording processing is temporarily stopped. A setting processing unit registers a field, based on the position information.

    Abstract: A drill has a first main body portion and a second main body portion. The first main body includes a chip discharging surface, a flank face, and an outer peripheral surface. A ridgeline between the chip discharging surface and the flank face constitutes a cutting edge. The chip discharging surface has an auxiliary flute surface provided in a form of a helix around a center axis, the auxiliary flute surface being contiguous to the cutting edge, the auxiliary flute surface being recessed in a direction opposite to a rotation direction of the drill. An auxiliary cutting edge portion has a first end portion and a second end portion. When viewed in a direction along the center axis, a value obtained by dividing the maximum value of the diameter of the second main body portion by the diameter of the first main body portion is 1.5 or more.
