作業機械
Document Type and Number:
Japanese Patent JP6843039
Kind Code:
B2
Abstract:
Provided is a work machine with which an operator can easily perform semi-automatic excavating shaping work at an intended excavation velocity. An information processing device calculates a target velocity of a work point at a predetermined position on a work implement on the basis of each of operation signals of operation devices, calculates a distance between the work point and a target surface on the basis of posture information of driven members and position information of the target surface, corrects a velocity component of the target velocity, the velocity component being perpendicular to the target surface, according to the distance such that the work point does not penetrate the target surface, and performs, before calculating the target velocity, weighting on each of the operation signals of the operation devices according to contribution to a velocity component of the work point, the velocity component being parallel to the target surface, on the basis of the posture information of the driven members and the position information of the target surface.
