A method for automatic process monitoring during continuous generating grinding of pre-toothed workpieces, which permit early detection of grinding wheel breakouts. A generating grinding machine is used to machine multiple workpieces by clamping them onto at least one workpiece spindle and successively moving them into generating engagement with a grinding wheel. At least one measured variable is monitored during the machining to indicate if a grinding wheel breakout exists. If a grinding wheel breakout is indicated, the grinding wheel is examined automatically by moving a dressing tool over the tip region of the grinding wheel and generating a contact signal. A breakout is determined by analyzing the contact signal and, if present, the grinding wheel is dressed as often as necessary in order to eliminate the grinding wheel breakout. Alternatively, the checking of the grinding wheel is carried out directly at the first dressing stroke.

The invention relates to a method for modifying the geometry of gear wheel tooth flanks with a tool with a toothing that engages with the gear wheel during a precision machining. A varied profile is produced on the tool over the width of the tool, in that during a dressing procedure a dressing wheel is moved along the tooth flank of the tooth to be dressed. The width of the teeth of the dressing wheel is much smaller than the width of the tool. In order to cover the width of the tool a length must be covered corresponding to a multiple of the width of the teeth of the dressing wheel. After the dressing, the precision machining of the gear wheel is carried out with the tool. Since the dressing wheel is moved with a changing pitch and a changing crossed axes angle relative to the tool, the modification of the tooth flank geometry can be reproduced in the tool. A modification of the crossed axes angle dependent on the helical angle of the tool takes place with equalisation of the helical angle of the tool changing over the width of the teeth of the tool. 1. A method for modifying the geometry of the tooth flanks of a gear wheel with the aid of a tool , which has a toothing engaging with the teeth of the gear wheel during a precision machining , wherein the following working steps are performed:a) forming a profile on the tool varying over the width of the tool, in which a dressing wheel is moved during a dressing procedure along the tooth flank of the tooth to be respectively dressed, wherein the width of the teeth of the dressing wheel engaging with the tool to be dressed is smaller than the width the tool to be dressed to such an extent that, in order to cover the width of the tool to be dressed, the dressing wheel has to be moved by a length in a direction that corresponds to a multiple of the width of the teeth of the dressing wheel, andb) precision machining of the gear wheel with the tool that has been dressed in this way,wherein the dressing wheel during the ...
