Abstract

Abstract: By means of orthogonal experiment,the effect of cutting factors(cutting speed,feed rate,depth of cut) on cutting forces is studied when dry cutting 304 austenitic stainless steel (0Cr18Ni9) with Al₂O₃/(W,Ti) C/CaF₂ gradient self-lubricating ceramic tool.Orthogonal table is used to perform the analysis of variance and F-test to confirm the primary and second order and significant influence of cutting parameters on cutting forces;empirical formula of main cutting force is established by exponential regression analysis.It can be indicated that main cutting force may be smaller than radial force in given range of cutting parameters.The result shows from F-test that feed rate and depth of cut have significant effect on cutting force.Main cutting force and radial force increase with the increasing feed rate and depth of cut.

Key words: gradient self-lubricating ceramic tool, austenitic stainless steel, cutting force, regression analysis
