Wear resistance behavior of striated tool for cross wedge rolling

Abstract

PurposeThe purpose of this paper is to investigate the wear resistance behavior of the striated tool for cross wedge rolling (CWR).Design/methodology/approachA mechanical-thermal coupled, temperature-dependent FE wear model was developed to explore the wear behaviors for striated CWR tools. To verify the proposed FE model, a newly developed measuring device was also developed to measure wear on the tool ridge. To find the impact order of the parameters of striate unit, orthogonal experiment was carried out.FindingsThe experimental and numerical results both indicate that the wear resistance of striated tool is better than that of smooth tool. Minimum tool ridge wear can be achieved by choosing proper tool contact temperature with striated units on crossed ridge. The order of the striation geometrical factors’ impact on ridge wear is striation width > striation interval > striation length.Research limitations/implicationsBecause of the specified tool, the research results may lack generalizability. Therefore, researchers are encouraged to test the proposed propositions further.Originality/valueIt is shown that the wear resistance of striated CWR tool is better than that of smooth tool. The information may help CWR manufactures to design and produce tools with less wear.
