Abstract

A profile working machine includes a support portion, a working portion, and a drive and control system. The machine also includes displacement sensors for detecting the present relative displacements between the support portion and working portion, a load sensor for detecting each working reaction force exerted to the working portion, a memory unit for storing values corresponding to a predetermined suitable working reaction force detected by the load sensor, a deviation computing unit for computing the deviation of each working reaction force from the values stored in the memory unit, and a displacement computing unit for computing, based on the deviation determined by the deviation computing unit and the present relative displacement detected by the displacement sensors, corrective relative displacements of the support portion and working portion required to bring the difference to 0, whereby the spatial orientation of the load sensor is maintained constant relative to the direction of the suitable working reaction force.
