【Abstract】 This article mainly discusses the way to machine the bolted node sphere. It gives the detail about an approach with which a virtual center of sphere can be machining datum, the way of dividing and clamping through two numerical-controlled axes. Meanwhile, the whole design scheme of a machining center for bolted node sphere’s manufacturing and its control system as well as working circulation are illustrated. All those provide a new processing technology and a high precision and efficiency equipment for machining of these parts.更多还原
