In this work, conventional (non-coherent), coherent-jet, and high pressure coolant delivery systems are compared for profile creep-feed grinding, under non-continuous dressing conditions. To facilitate this comparison, an analytical method of determining the available flow (coolant that hits the wheel or workpiece) was presented. The coolant delivery systems were compared for five different feed rates. At each feed rate the form error was measured using a coordinate measuring machine at five cross sections along the workpiece. The high-pressure coolant delivery system had the lowest form error and had an available flow of only 1.7 Llmin. The non-coherent jet had the second best form error and had an available flow of 17 Llmin. The coherent jet had the highest form error with an available flow of 39 Llmin.
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.
