Abstract:
A method for shot peening wherein the work is processed by
being hit by shot materials that are shot by compressed air,
and a machine for carrying out the method are provided. By
the present invention the status of a work can be measured
while the work is being processed. The requirements for
maintaining and calibrating the sensor that is used for the
measurement are reduced because the wear of the sensor is
prevented. The method for shot peening is to process a work
by shooting the shot materials with compressed air from a
shooting nozzle against the work. The shooting nozzle is
equipped with a transducer that detects elastic waves and
transduces them to high-frequency electrical signals. The
elastic waves are generated when the shot materials pass
through the shooting nozzle. The characteristic values of the
shot materials, which pass through the shooting nozzle, are
measured and monitored based on the signals.
