Abstract
A method for the finishing treatment of work pieces, uses a processing device including a tool spindle for a processing tool and a numerically controlled (NC) feeding device. The force of the contact pressure applied to the work piece on the side of the work piece is measured and the measured force values are supplied to the numerical control (NC), which determines and fixes the feed rate at which the processing tool is advanced against the work piece. The finishing treatment is carried out in a force-controlled operating mode, in which the feed rate is controlled depending on the force of the contact pressure acting on the processing tool. A processing device is employed whose tool spindle is movably supported in the direction of the feeding movement on leaf springs on the feeding device. The processing device includes a force-measuring device effective between the tool spindle and the feeding device and operating substantially free of deformation. In the force-controlled operating mode, feed rate values are allocated to the values measured by the force-measuring device at a cycle control frequency preset by the numerical control (NC), whereby the allocation is fixed according to a damping function.
