中文摘要:
      目的 稳健设计螺旋铣孔对难加工材料钛合金加工件的切削参数(切削深度、每齿进给量和主轴旋转速度)。方法 用正交优化法制定一套试验方案并实施,使用粗糙度量仪、三坐标、显微镜等对钛合金孔表面粗糙度(Ra)、孔径精度和出口端毛刺高度进行测量和分析;在此基础上,利用试验数据分析影响因素水平极差和贡献率,优选出一组切削参数组合(主轴旋转速度2000 r/min、每齿进给量为0.07 mm和切削深度0.25 mm/r),以此为基准,对待加工钛合金工件表面粗糙度进行预测;为进一步验证预测值满足孔表面质量标准,然后对钛合金加工件试验分析。结果 结果表明,孔表面粗糙度介于0.55~0.75 μm,孔径精度介于H7~H9,很好地达到了航天或汽车工业对钻孔粗糙度的技术要求。结论 由此可见,使用该方法,不仅可获得稳健设计切削参数,还可改善钛合金螺旋铣孔切削工艺。
英文摘要:
      The work aims to soundly design cutting parameters of titanium alloy machined parts, including cutting depth, feed per tooth and spindle rotation speed in helical milled hole for difficult-to-cut materials. A set of testing program was formulated and carried out based on orthogonal optimization method. Roughness measuring instrument, coordinate measuring machine and microscope were used to measure and analyze surface roughness (Ra), diameter accuracy of titanium alloy hole and burr height at outlet end. On this basis, horizontal range and contribution rate of influencing factors were analyzed by combining with experimental data, and then a set of cutting parameters was selected (spindle rotation speed of 2000 r/min, feed per tooth of 0.07 mm and cutting depth of 0.25 mm/r). Then the surface roughness of titanium alloy workpiece to be machined was predicted. The titanium alloy machined part was tested and anlyzed in order to verify if the predicted value conformed to surface quality standards of the hole. Surface roughness of helical milled hole ranged from 0.55 to 0.75 μm while diameter accuracy was within H7 and H9, well meeting the technical requirements for drill hle roughness in aerospace or automobile industry. Therefore, not only cutting parameters in robust design are obtained by using this method, but also cutting technology of titanium alloy helical milled hole is improved.
