影响微尺度铣削加工质量的因素中,工艺参数相对于其他动态变化的因素是可控的。针对微尺度铣削工程材料黄铜H68,基于所开发的微尺度铣削机床,应用Taguchi方法,通过实验的方法,以表面粗糙度作为加工质量评价指标,对工艺参数展开了研究。通过对实验结果的极差分析与方差分析,确定了3个关键工艺参数轴向切深、径向切深和每齿进给量对表面粗糙度的影响趋势。结果表明:径向切深对于微尺度铣削黄铜H68影响最大,其次是每齿进给量与轴向切深。本研究对于微尺度铣削类似的延展性材料提供了方法与工艺参考。 Of the factors that affect the quality of micro-scale milling, the process parameters are controllable relative to other dynamically changing factors. Aiming at the micro-scale milling of engineering material brass H68, the Taguchi method was used to develop the micro-scale milling machine tool. The surface roughness was taken as the evaluation index of processing quality through the experimental method. Through the range analysis and variance analysis of the experimental results, the influence of axial cutting depth, radial cutting depth and feed per tooth on the surface roughness of three key process parameters was determined. The results show that the radial depth of cut has the greatest effect on micro-scale milling brass H68, followed by the feed per tooth and the axial depth of cut. This study provides a method and process reference for the microscale milling of similar ductile materials.
