Abstract

See full text

To provide a work machine that enables enhancement of shaping accuracy near a boundary line between two adjacent target surfaces. A controller 10 extracts, from among a plurality of target surfaces, a second target surface S2 that is a target surface adjacent to a first target surface S1, calculates a boundary line L2 between the first target surface S1 and the second target surface S2, and, prior to a work tool 6 passing the first boundary line L2, corrects a control signal for a posture control actuator 6c such that the angular difference EL between a reference line L1 set on the work tool 6 and the boundary line L2 becomes small.
