外文摘要：In this paper, the centerless finishing process of bearing cylindrical roller made of AISI 52100 steel using free abrasives and soft pad was investigated by the Taguchi method in the experiments and simulation, with the aim of improving the roundness. The rounding and material removal process was simulated based on the improved model. The test runs of experiments and simulation were designed according to a standard orthogonal array in which four factors included loading force, abrasives concentration, particle size, and error, and each factor had three levels, as well as the total number of parameter combinations was nine. The signal-to-noise (S/N) ratio was applied in experimental data processing, representing both the average (mean) and the variation (scatter). According to the analysis of variance (ANOVA) by S/N ratio, it is indicated that the loading force makes the largest contributions respectively accounting for 72% in roundness and 54% in material removal rate (MRR), the abrasive concentration almost has no contribution in roundness but has one accounting for 24% in MRR, and the particle size has contributions respectively accounting for 21% in roundness and 13% in MRR. Through the analysis of level average response, the optimal parameter combination was chosen as loading force of 60 N, abrasives concentration of 10 wt%, and particle size of 127 mu m. In the centerless finishing experiments under the optimal conditions, the roundness was improved from an initial 0.71 to a final 0.32 mu m after 12 min of processing at the MRR of 0.44 mu m/min.
