Abstract
Abstract There are gaps and misconceptions in our understanding of tool–chip friction. The present paper presents a novel method of studying the tribological properties of cupronickel B10 during dry cutting. Three types of experiments—the split Hopkinson pressure bar test, SRV test and orthogonal cutting test—were conducted. Following the tests, topographies of the worn surfaces were analyzed employing scanning electron microscopy. The temperature, normal load and cutting speed effect coefficient were obtained by taking full advantage of each test. Finally, a new empirical friction model for the dry cutting of cupronickel B10 at the tool–chip interface was obtained. The model clarifies the mechanisms of tool–chip friction.
