Method for grinding a toothing or a profile of a workpiece

A method for grinding a toothing or a profile of a workpiece by a grinding tool in a grinding machine, in particular generating grinding of a gear wheel with a grinding worm,

• wherein the grinding tool is received on a tool spindle and the tool spindle is rotated by a first drive motor, so that a tool drivetrain is present, and
• wherein the workpiece is received on a workpiece spindle and the workpiece spindle is rotated by a second drive motor, so that a workpiece drivetrain is present,
• wherein at least one angular acceleration sensor is arranged in the area of the tool drivetrain and/or in the area of the workpiece drivetrain, wherein the values for the angular acceleration of the tool spindle and/or the workpiece spindle recorded by the angular acceleration sensor are transmitted to a data processing system and evaluated by the latter,
• wherein the measured signal of the angular acceleration is subjected to a frequency analysis,
• wherein the individual frequency components are determined with regard to their amplitude,
• wherein respective limit values are predetermined for the amplitudes of the frequency components, wherein a signal is output by the data processing system when at least one of the limit values is exceeded, and wherein the frequency components are monitored only with regard to their amplitude.
