The study aims to fabricate large metal components with overhangs built on cylindrical or conical surfaces with a high dimensional precision. It proposes methods to address the problems of generating tool-paths on cylindrical or conical surfaces simply and precisely, and planning the welding process on these developable surfaces.,The paper presents the algorithm of tool-paths planning on conical surfaces using a parametric slicing equation and a spatial mapping method and deduces the algorithm of five-axis transformation by addressing the rotating question of two sequential points. The welding process is investigated with a regression fitting model on a flat surface, and experimented on a conical surface, which can be flattened onto a flat surface.,The paper provides slicing and path-mapping expressions for cylindrical and conical surfaces and a curvature-speed-width (CSW) model for wire and arc additive manufacturing to improve the surface appearances. The path-planning method and CSW model can be applied in the five-axis fabrication of the prototype of an underwater thruster. The CSW model has a confidence coefficient of 98.02% and root mean squared error of 0.2777 mm. The reverse measuring of the finished blades shows the residual deformation: an average positive deformation of about 0.5546 mm on one side of the blades and an average negative deformation of about −0.4718 mm on the other side.,Because of the chosen research approach, the research results may lack generalizability for the fabrication based on arbitrary surfaces.,This paper presented an integrated slicing, tool-path planning and welding process planning method for five-axis wire and arc additive manufacturing.

用于五轴线材和电弧增材制造的基于圆柱面或圆锥面的工艺规划

该研究旨在制造具有高尺寸精度的圆柱或圆锥表面悬垂的大型金属部件。提出了简单精确地在圆柱或圆锥面上生成刀具路径以及在这些可展曲面上规划焊接过程的方法。本文提出了使用参数化切片方程在圆锥面上规划刀具路径的算法以及空间映射方法，并通过解决两个连续点的旋转问题推导出五轴变换算法。焊接过程在平面上用回归拟合模型进行研究，并在圆锥面上进行实验，圆锥面可以压平到平面上。该论文提供了圆柱和圆锥曲面的切片和路径映射表达式，以及用于线材和电弧增材制造的曲率-速度-宽度 (CSW) 模型，以改善表面外观。路径规划方法和CSW模型可应用于水下推进器原型的五轴制造。CSW 模型的置信系数为 98.02%，均方根误差为 0.2777 mm。成品叶片的反向测量显示残余变形：叶片一侧的平均正变形约为 0.5546 mm，另一侧的平均负变形约为 -0.4718 mm。,由于选择的研究方法，研究结果可能缺乏基于任意曲面的制造的普遍性。,本文提出了一种集成切片，
