The invention provides a method for manufacturing a vehicle wheel. The method includes a step of performing an edge treatment including flash removal of a spoke edge generated by lathe machining. The edge treatment uses a cutting tool for non-rotational machining, in which a machining blade having an R-shaped or polygonal C-shaped concave blade tip is formed so as to protrude from the outer peripheral surface of the tip side of a rod-shaped cutting tool connected to a rod-shaped shank. Provided is a machining machine using CNC control of four or more axes. The purpose of the present invention is to maintain a tool rotation direction angle within a range in which an R-shaped or polygonal C-shaped tip shape of a cutting tool can be transferred. The cutting tool is erected relative to the spoke surface, so that the blade tip of the machining blade abuts against the spoke edge and continuously moves relative to the spoke edge along the ridge line of the spoke edge for cutting. A processing surface of the same shape as an R shape or a polygonal C shape which is consistent with the shape of a blade tip of a cutting tool is continuously formed while the flash of the edge of the spoke is removed, so that a coating film can be stably formed on the processing surface of the edge of the spoke by a subsequent coating process.
本发明提供一种车辆用车轮的制造方法,具有进行包含由车床加工产生的辐条边缘的飞边去除的边缘处理的工序。边缘处理使用非旋转加工用的切削工具,其在与棒状的柄部连接的棒状切削工具前端侧外周面突出形成具有R形或多角C形的凹形状的刃尖的加工刃。使用四轴以上的CNC控制的加工机械。保持切削工具的R形或多角C形的刃尖形状能够转印加工的范围内的工具旋转方向角度。以将切削工具相对于轮辐面竖立的姿势使加工刃的刃尖与辐条边缘抵接并使其沿着辐条边缘的棱线连续地相对移动而切削。在对辐条边缘去除飞边的同时连续形成与切削工具的刃尖形状一致的R形或多角C形的相同形状的加工面,使得在该辐条边缘加工面上能够由之后的涂饰工序稳定形成涂膜。
