Claim:
1. A work machine control system that controls a work machine including a work unit with a working tool, the work machine control system comprising: a position detection unit that detects a position information item of the work machine; a generation unit that obtains a position of the work unit based on the position information item detected by the position detection unit and generates a first target excavation ground shape information item as an information item of an intersection portion of a first cut face which intersects a work unit operation plane as an operation plane for the work unit and is parallel to a vertical direction with respect to at least one target construction face which indicates a target shape; and a work unit control unit that performs an excavation control so that a velocity in a direction in which the work unit approaches an excavation target becomes equal to or less than a limitation velocity based on the first target excavation ground shape information item acquired from the generation unit, and wherein the work machine includes a swing body that has the work unit attached thereto and that swings about a predetermined axis, and wherein the work unit control unit performs the excavation control based on a velocity having a target velocity in a direction in which the work unit swings synthesized with a target velocity in a front to back direction of the working tool when the work unit is swinging along with the swing body.
