The growing demand for micro products of hard and brittle materials requires suitable manufacturing processes, which serve high structure quality and accuracy. Therefore, micro pencil grinding tools are used. While grinding hard and brittle materials the structure quality and accuracy depends on the material removal mechanism. This mechanism is a complex interaction between the process parameters, the material response and the tool geometry. In this paper the influence of the process parameters, particularly the cutting speed and the feed rate, on the material removal mechanism are discussed. Furthermore, a method for the analysis of the structure quality and accuracy and within the material removal mechanism is shown.
Sustainability in manufacturing became more and more important in the last years and, because of scarcity of resources, will become even more important in the future. In a process-oriented view, abrasive processes appear to be the worst manufacturing processes concerning sustainability due to their high required specific energies. In this paper a product-oriented view is proposed, taking the whole Life Cycle of the machined products into account. In doing so, it becomes evident that abrasive processes can enhance sustainability even when investing additional energy during machining.
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.
