A method for checking the rotation of mechanical workpieces which includes the steps of measuring the workpiece size, processing the measuring signals occurring to generate at least one signal responsive to the measurement of size variations of the workpiece and utilizing the signal for generating control signals to indicate the evenness of the rotation of the piece. An apparatus for practicing the method includes feelers adapted to be brought to the measuring position on the workpiece to supply signals responsive to the size, a processing unit adapted to process the measuring signals detected at succeeding moments to supply information on the geometrical features of the workpiece or its variations, delay and timing units to trigger the processing unit connected with the output of the processing unit and adapted to compare the signals at the output itself with preset reference signals and a consent unit connected with the comparison unit operable as a result of the evenness of the workpiece rotation.

A method for checking the operation of a grinding machine for the machining of rotating mechanical workpieces, substantially of circular cross-section, comprising the steps of: obtaining a measuring signal responsive to the workpiece size, this step being carried out both before and during the stock removing phases of the machining operation; processing the measuring signals occurring at subsequent time intervals, said processing step including generating at least one variable signal responsive to the measurement of size variations of the workpiece both before and during the stock removing phases of the machining operation; comparing the variable signal generated with a reference signal; utilizing the result of the comparison for providing a signal indicative of the evenness of the rotation of the workpiece; and utilizing the latter signal as a consent for the prosecution of the machining depending on whether the workpiece rotates evenly.
