Abstract:A better understanding of friction modeling is really important for producing more realistic finite element models of machining processes. This paper presents a methodology to determine the friction at the tool-chip interface. By matching the measured values of the cutting forces with the predicted results from finite element simulations (FEM), a revised friction model on the tool-chip interface is developed. Reasonable distribution of the stress, strain and strain-rate, as well as the temperature fields at th… Show more
scite is a Brooklyn-based startup 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 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.
