Abstract:This paper presents passive vibration control methodology in internal turning process with the use of hybrid nanocomposite coatings (nano-SiC/GFRE) on the surface of boring bar. Natural frequencies and damping ratio of different composition tool holders are obtained experimentally using impact hammer test. Three different configuration considered are: conventional (tool holder 1); nano-SiC/GFRE with 1% SiC (tool holder 2); and nano-SiC/GFRE with 2% SiC (tool holder 3). A better damping ability is noticed in th… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
