Abstract
In a work machine which includes a working head including a lifting and lowering unit including a working device and a first lifting and lowering device which lifts and lowers the working device, and a second lifting and lowering device which lifts and lowers the lifting and lowering unit, a positional deviation (Δx, Δy) of the working device in a direction which is perpendicular to a lifting and lowering direction is eliminated. Since the positional deviation is caused by both an inclination of a lifting and lowering axis line Lof the working device by the first lifting and lowering device and an inclination of a lifting and lowering axis line Lof the lifting and lowering unit by the second lifting and lowering device, based on positional deviation data a target moving position is corrected.
