Boring tests were conducted on aluminum alloys to investigate the effects of cutting fluid on machining performance. Statistically designed experiments were used to examine the role of such process variables as tool geometry, cutting conditions, work material, cutting fluid presence, cutting fluid concentration, and hydraulic oil contamination of cutting fluid. Responses for the boring tests were surface texture, forces, and observed built-up edge (BUE). The results indicate that the cutting fluid presence, oil concentration, and hydraulic oil contamination do not play a significant role in process performance under the conditions tested.
In this work, the Eh -pCl diagram of the CuCl-HzD system was established, and the kinetics of copper dissolution in cupric chloride solution were studied with an emphasis on possible difficulties that may occur during copper electrowinning. The results were used to guide an investigation of copper electrowinning from cupric chloride solution.
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.
