Abstract
To provide a work machine that enables enhancement of shaping accuracy near a boundary line between two adjacent target surfaces. A controllerextracts, from among a plurality of target surfaces, a second target surface Sthat is a target surface adjacent to a first target surface S, calculates a boundary line Lbetween the first target surface Sand the second target surface S, and, prior to a work toolpassing the first boundary line L, corrects a control signal for a posture control actuatorsuch that the angular difference Ebetween a reference line Lset on the work tooland the boundary line Lbecomes small.
