WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/195262
Kind Code:
A1
Abstract:
To provide a work machine that enables improvement of shaping precision near a boundary line between two adjacent target faces. A controller 10 extracts, from a plurality of target faces, a second target face S2 that is a target face adjacent to a first target face S1, calculates a boundary line L2 between the first target face S1 and the second target face S2, and prior to a tool 6 passing the first boundary line L2, corrects a control signal of an attitude control actuator 6c such that the angular difference EL between a reference line L1 and the boundary line L2, set to the tool 6, becomes smaller.
