ABSTRACT:
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.
