摘要: 为提高整体叶轮的粗加工效率,弥补目前商用计算机辅助制造软件在五坐标插铣加工能力方面的不足,研究了直纹面叶轮五坐标插铣加工的关键技术。根据直纹面叶片的偏移边界矢量,利用四元数插值方法计算插铣加工的刀轴矢量,提出并推导了五坐标插铣加工的行距和步距计算公式,保证了插铣加工的材料去除率和加工效率。依据上述算法自主开发了整体叶轮五坐标插铣加工专用计算机辅助制造软件,并对该软件生成的刀具轨迹进行了仿真和实际加工验证。结果证明,该方法在一定程度上提高了叶轮零件的粗加工效率。

Abstract: To improve the efficiency of integrated impeller rough machining, and to overcome the five-axis plunge milling deficiency of commercial Computer Aided Manufacturing (CAM) software, key technologies in ruling surface impeller plunge milling were studied. According to the offset boundary vector of ruling surface blade, interpolated cutter axes were generated by using quaternion interpolation algorithm, row space and step distance calculating algorithm were deduced to ensure the material removal rate and machining efficiency. Integrated impeller plunge milling special CAM software was developed. The generated cutting path was simulated and verified in practical processing. Simulation and experimental results showed that the impeller parts rough machining efficiency was improved by this method.

Key words: plunge milling, integrated impeller, computer aided manufacturing, cutting-path planning
