Abstract
The invention includes systems and methods of cleaning, for example, machining waste from holes in work pieces such as metal castings. The invention depends upon submerging, in a liquid, openings of the respective holes to be cleaned, aligning a nozzle with each such hole, with liquid disposed between the nozzle and the hole, and expressing one or more blasts of pressurized gas from the nozzles, through the intervening liquid, and into the holes. The apparatus contemplates a system having an array of nozzles positioned and arranged around the work piece such that a nozzle is positioned at each hole to be cleaned. The apparatus can be configured for cleaning a family of related work pieces, having differing arrangements of holes to be cleaned, by providing a nozzle for each hole included in the combination of all the arrays of all the work pieces to be cleaned.
