针对网架螺栓节点球现行加工方法的不足 ,提出了虚拟球心基准、正交合成分度的方法 ,实现了螺纹孔在全球面任意分布的螺栓节点球的无基准加工 ,给出了基于正交合成分度方法的分度角度计算方法 ,为螺栓节点球数控加工自动编程做好了准备
Aiming at the deficiency of current machining method of grid bolt node ball, a method of virtual centering and orthogonal compositional indexing is proposed, and the non-datum machining of bolt node ball distributed randomly in the global surface is realized. Intersection composition method of indexing angle calculation method for the preparation of bolt node ball NC machining automatic programming
