Abstract

An apparatus includes a positioning system; a surface indicator system to collect an indication data set from a surface of a component utilizing a fluorescent penetration process; an indication data processing system to create an output data set in response to the indication data set utilizing a fuzzy logic algorithm; and a microprocessor to provide at least one surface variance in response to the indication data set and the output data set. A method including conducting a surface indication technique for a component; utilizing a positioning algorithm to manipulate positioning equipment in response to the component; directing an indication source to a surface of the component; collecting an indication data set in response to directing the indication source; applying a fuzzy logic analysis in response to the indication data set to provide an output data set; and providing at least one surface variance in response to the output data set.
