Abstract
A method and apparatus for stripping foreign matter from holes in a substrate, such as a turbine component, which includes using a scanner to locate the hole and operating a water jet apparatus to direct a water jet or an abrasive water jet into the hole for stripping. A CAD model of the original turbine component may be used in the control system of the water jet apparatus to initially locate the scanner at the general or theoretical location of the hole. A reverse flow of low pressure water may be provided to further clear foreign matter from the hole.
