1. A method for finishing a work piece at a preset force value comprising the steps of:

  • (a) providing a processing device having a tool spindle for a processing tool movably supported in a direction of feed movement via leaf springs on a feeding device coupled to a numerical control (NC);

    (b) measuring a contact pressure force applied by the processing tool on a side of a work piece using a force-measuring device disposed between said tool spindle and said feeding device operating substantially without deformation;

    (c) allocating feed rate values to corresponding measured force values at a cycle control frequency preset by said numerical control; and

    (d) supplying contact pressure force values to the said numerical control for control of a feed rate at which the processing tool is advanced against the work piece in accordance with a selected damping function for a particular application so that in carrying out a finishing treatment in a force-controlled operating mode the feed rate increases with decrease in measured force value and decreases with increase in measured force value, until the measured force value substantially corresponds with the preset force value.
