Abstract
A profile working machine is equipped with a support for holding a work in place, a working tool for machining the work, and drive and control systems for controlling the relative displacements between the support and the working tool. The profile working machine is to machine the work into a desired profile. The profile working machine is additionally provided with a load sensor for detecting each force and moment to be developed between the working tool and the work, a first computing unit for computing a working point and a tangential plane extending through the working point and in contact with the working tool, on the basis of the force and moment detected by the load sensor, and a second computing unit for computing, based on the working point and the tangential plane computed by the first computing unit and the forces detected by the load sensor, the values of the relative displacements between the working tool and the support in order to keep the magnitude and the direction of a reaction force exerted on the working tool on predetermined values.
