金属切削加工中，冷却方式的选择影响着工件的变形机理，关系到工件的尺寸精度和表面光洁度。钛合金在机械加工条件下的变形机制与常用的工业材料有很大的不同。因此，冷却方法对加工钛的尺寸精度和表面光洁度的影响特别令人感兴趣。本文通过实验和分析研究了冷却方式和切削参数对钛合金车削件两个主要尺寸精度特性--直径误差和圆度以及表面光洁度的影响。资料分析方法有传统分析法、Pareto变异数分析法及田口法。结果表明，冷却方式对圆度误差影响显著（贡献率为76.75%），对直径误差影响中等（贡献率为25.00%），对表面光洁度影响不显著（贡献率为0.16%）。
AbstractsIn metal cutting, the choice of cooling method influences the deformation mechanism, which is related to the dimensional accuracy and surface finish of the parts. The deformation mechanism of titanium alloys under machining conditions is known to be very different from that of commonly used industrial materials. Therefore, the effect of cooling methods on dimensional accuracy and surface finish in machining titanium is of particular interest. This paper investigates experimentally and analytically the influence of cooling method and cutting parameters on two major dimensional accuracy characteristics of a turned titanium part—diameter error and circularity, and surface finish. Data were analyzed via three methods: traditional analysis, Pareto ANOVA, and Taguchi method. The findings indicate that the cooling method has significant effect on circularity error (contribution ratio 76.75 %), moderate effect on diameter error (contribution ratio 25.00 %), and negligible effect on surface finish (contribution ratio 0.16 %).
