In the maintenance of precision machines, regular cleaning is critical to the performance and service life of parts. However, with the remarkable improvements in manufacturing technology, the shapes of machine parts have become more complex such that more efficient cleaning technology is required. This study clarifies the effects of different shapes of machine parts on microbubble cleaning with surfactants and investigates efficient cleaning methods. In the previous study, experiments were conducted on flat specimens. In this study, in addition to flat specimens, three-dimensional specimens are prepared, and experiments are conducted. A cleaning solution containing a surfactant are filled with microbubbles and cleaning experiments are conducted. Experimental results between planar and three-dimensional specimens are then compared. Results showed that the cleaning effect of the three-dimensional specimens was worse than that of flat specimens on the microbubble cleaning process when certain surfactants were combined.
