1. A work machine comprising:
a work implement;
a work implement position sensor that obtains a position of the work implement;
an operation device provided to be able to receive an operation of operator;
a controller; and
a storage that records position data indicating the position of the work implement as existing topography data when the operation of the operator is received at the operation device;
wherein the operation device includes one or more of a record button or a record switch,
the controller calculates a distance between a designed topography of an execution object and a contour point that is closest to the designed topography of the construction target among a plurality of contour points of the execution object according to the position of the work implement acquired by the work implement position sensor, and
the controller records position data indicating the position of the working machine of the closest contour point as the existing topography data when the operation of the operator is received at the one or more of the record button or the record switch of the operation device.
 
3. A execution management device comprising:
a work implement position sensor that obtains a position of a work implement;
an operation device provided to be able to receive an operation of operator;
a controller; and
a storage that records position data indicating the position of the work implement as existing topography data when the operation of the operator is received at the operation device; wherein
the operation device includes one or more of a record button or a record switch,
the controller calculates a distance between a designed topography of an execution object and a contour point that is closest to the designed topography of the construction target among a plurality of contour points of the execution object according to the position of the work implement acquired by the work implement position sensor, and
the controller records position data indicating the position of the working machine of the closest contour point as the existing topography data when the operation of the operator is received at the one or more of the record button or the record switch of the operation device.
 
5. A work machine control method comprising:
obtaining a position of a work implement of a work machine from a work implement position sensor;
calculating a distance between a designed topography of an execution object and a contour point that is closest to the designed topography of the construction target among a plurality of contour points of the execution object according to the position of the work implement acquired by the work implement position sensor; and
recording position data indicating the position of the working machine of the closest contour point as existing topography data when an operation of an operator is received at one or more of a record button or a record switch of an operation device, wherein a storage records the position data indicating the position of the work implement as the existing topography data when the operation of the operator is received at the one or more of the record button or the record switch of an operation device.
