    摘要:

    针对整体叶轮高速铣削加工,开展了以切削速度、每齿进给和切削深度为试验因素,以叶片的表面粗糙度和加工时间为试验指标的正交切削试验,应用田口法对试验结果进行分析,初步确定铣削要素对试验指标的影响程度。采用方差分析方法对正交试验结果进行进一步处理,得到各铣削要素对试验指标的贡献率,确定了叶片铣削的最佳参数组合。经过整体叶轮加工验证,采用优化后的切削参数保证了叶片表面粗糙度Ra08 μm,并且加工效率提高3倍,实现了整体叶轮的高效加工。

    Abstract:

    Aiming at high speed machining of integral impeller, orthogonal cutting experiments considering the cutting speed, feed rate per tooth and cutting depth were performed. Taguchi method was applied to analyze the experiment results.The influences of cutting parameters on surface roughness and cutting time were preliminarily determined.Then, analysis of variance was used for further processing of the experimental results, the contribution of cutting parameters to experimental results and the optimal parameter combination were acquired. After the machining verification of integral impeller, the surface roughness of the blade is ensured to Ra08 μm, and the processing efficiency is improved 3 times, so the high efficiency machining of integral impeller is achieved.
