| Abstract: | An eddy current scanning system for disk and shaft type metal parts has been developed, which is comprised of computer, eddy current inspection instrument, motor control unit, four axis scanner, probe and some accessorial fixtures. Adapting well to the inspection of most disk and shaft type parts, the system can make automatic scanning smoothly on plane surface, discal surface, cylindrical surface, and conical surface of parts. The key technologies concerning the system design and actualization are analyzed in this paper, and some experiment results are provided. It was proved that the use of this system can greatly improve test sensitivity comparing with traditional manual testing, as well as provide intuitionistic imaging result. |
