A commercial ultrasonic test facility has been interfaced to a medium-sized multiuser computer. The large volumes of data, formerly correlated to flaw size and flaw location manually, are now automatically accumulated and analyzed, and the results are plotted within a matter of minutes. The control system is capable of positioning the ultrasonic transducer with four degrees of motion-three linear and one angular. The data handling system offers the flexibility to allow implementation of nearly any future test requirements.nThe system is now operational and is in daily use in a development laboratory. Surfaces of revolution and flat plates have been inspected with good results. Fourier transforms of ultrasonic waveforms are handled routinely. The multiuser computer configuration gives the user the impression of having a dedicated computer at his disposal.
