摘　　要：针对船用螺旋桨传统加工方法效率、精度较低的问题,本文基于2套XYZ-3RPS混联加工装置,研究了螺旋桨桨叶的双面协同加工方法。在此基础上,根据螺旋桨的几何特性开发了后置处理算法。通过两侧刀位数据对齐实现了两侧刀具在桨叶表面内部区域的对称加工;通过两侧刀具在桨叶表面边缘区域的错位走刀,避免了碰撞;通过分段五次插值及超限校验算法,实现了平滑稳定的加工过程。最后,通过仿真和实际加工实验,验证了后置处理算法的有效性与可行性。The double-sided collaborative machining method,which is based on two sets of XYZ-3RPS hybrid machine tools for propeller blades,is investigated in this study to address the low efficiency and accuracy of traditional machining methods for marine propellers.On this basis,a post-processing algorithm is developed according to the geometric characteristics of the propeller.First,symmetrical machining of the internal area of the blade surface is achieved by aligning the bilateral cutter location data.Second,the collision of the bilateral cutters is avoided by staggered feeding at the edge area of the blade surface.Third,a smooth and stable machining process is ensured by the piecewise quintic interpolation and transfinite checking algorithm.Finally,the validity and feasibility of this algorithm are verified through simulation and machining experiments.
