A method for machining and measuring workpieces includes: machining a workpiece by a gear cutting process, wherein a tooth flank of the workpiece is produced or machined; measuring an actual geometry of the tooth flank produced by the gear cutting process by a measuring process; determining a deviation of the actual geometry from a predetermined nominal geometry of the tooth flank; determining a corrected gear cutting process for at least partially reducing the deviation; and machining the workpiece and/or a further workpiece by the corrected gear cutting process. The determination of the corrected gear cutting process for at least partial reduction of the deviation has the specification that a distinction is made between first and second evaluation areas of the tooth flank, wherein first and second permissible deviations of the actual geometry from the nominal geometry is specified for the evaluation areas of the tooth flank, respectively.

Feed rate scheduling methods include measuring a topography of a grinding wheel of a machine tool, calculating a topography parameter using the topography, and calculating a feed rate scheduling parameter for a toolpath of the grinding wheel based on the topography parameter. The topography may be measured using microscopy. The topography parameter may include a plurality of parameters including a density of crystals at a given depth (C(h)) of the grinding wheel and/or an area fraction of crystals protruding at a given depth (α(h)) of the grinding wheel. The feed rate scheduling parameter may include a grinding wheel feed rate, a grinding wheel spin rate, and/or a grinding wheel cutting depth, among other parameters.

One or more workpieces having a desired gear geometry may be produced by means of a suitably dressed tool which is respectively dressed by a dresser after the carrying out of one or more machining steps before further machining steps are carried out at the same workpiece or at further workpieces. A relative position between the dresser and the tool may be changed by a corresponding additional adjustment of the axes of movement of the dressing machine in a later dressing process with respect to an earlier dressing process in addition to the smaller center distance resulting from the smaller tool diameter.

A position compensation system of a tool changer includes a storage unit for storing a coordinate indicating a reference position of a turret, a rotary position coordinate detector for detecting the rotary position coordinate of the turret, a compensation necessity determiner for determining whether or not it is necessary to perform a rotational compensation to return the turret to the reference position, in accordance with a rotational deviation of the detected rotary position coordinate from the stored rotary position coordinate, and a compensation request part for requesting an operation or work related to the rotational compensation when it is determined that the rotational compensation needs to be performed.
