Eddy-current monitoring of the surface quality of rollers in centerless grinding

The Reconstruction of Crack in Surface Based on Virtual Instrument

“…[2,3] Recent developments in the field of eddy current in imaging encourage looking at the crack reconstruction not only as a theoretical problem but also taking into account its practical use. [2,3,4,5,6] But the crack reconstruction has not been fully developed because eddy real-time imaging is very difficult. At present eddy imaging technologies mainly include Impedance C scan, Layer-divided and Magic-light converting.…”

“…So research for the reconstruction of surface crack is necessary. [2,3,4,5] Virtual Instrument is based on computer, the product that combines instrument technology with computer. Computer and instrument's combination is one of the instrument development's key directions.…”
