The pattern recognition techniques have been applied to fluorescent magnetic particle testing for automatic inspection of defects, and a development has been made on automatic conditioning machine that can remove defects accurately even on slightly curved billets.
Installing the defect inspection equipment and the conditioning machine on a transfer line that is controlled by a process computer, the authors have established a fully automatic inspection and removal system for the defects of spuare billets.
Emphasis is placed in this paper, on showing the mechanism of the defect inspection equipment and the conditioning machine, and features of the whole system, including the transfer system.
