Work machine

A work machine comprising:

• a lower traveling body;
• an upper turning body mounted on the lower traveling body capably of turning;
• a work device rotatably attached to the upper turning body capably of performing a work motion, the work device including a control target part;
• and
• a controller that sets target trajectory information and controls driving of the upper turning body and the work device so as to make the upper turning body and the work device perform a target motion of moving the control target part in accordance with the target trajectory information, the target trajectory information containing a plurality of target points on a target path of the control target part included in the work device and an inter-target-point time that is a target value of a time in which the control target part moves between adjacent target points among the plurality of target points, wherein:
• the controller is configured to make a shift of at least one of a start point and a terminal point of the plurality of target points of the next target motion and make a correction of the target trajectory information when judging that work including the target motion has reached a predetermined stage;
• and
• the correction of the target trajectory information includes a correction of the inter-target-point time based on a change from a previous movement amount to a new movement amount, the previous movement amount being an amount by which the control target part moves from the start point to the terminal point before the shift of the at least one of the start point and the terminal point, and the new movement amount being an amount by which the control target part moves from the start point to the terminal point after the shift of the at least one of the start point and the terminal point.
