摘要
为提升轴类零件加工精度,以风力驱动器叶轮轴为例,针对传统的加工工艺中存在的效率不高、精度较低问题,提出了数控车床与数控铣床联合加工优化工艺。建立零件三维模型,确定机床坐标系与工件坐标系,设定刀具工作参数和数控编程。分别选用原工艺和改进工艺下的加工工件样品进行对比,观察叶轮轴叶片的加工误差。结果表明,使用改进工艺可缩小R5圆弧加工尺寸的分布范围,加工精度有了明显提升,可确保轴类零件在高速转动时保持良好、稳定的工况,有效将误差控制在允许范围内。
In order to improve the accuracy of axis parts processing,through taking wind drive vane shaft as an example,the study proposes optimization technology of the combination of numerical control machining and numerical control milling machine according to low efficiency and accuracy of traditional processing.The study establishes 3D component model,confirms machine tool and workingpiece coordinate system,and designs tool working parameter and numerical control programming.The results show that the utilization of improved technology can reduce the distribution scope of R5 arc working size,significantly improves processing accuracy,ensures axis parts to keep good and stable working situation when turning in high speed,and effectively controls error in the permissible range.
