Aiming at hyperboloid NOMEX honeycomb of comgposite materials, this article focused on the honeycomb CNC milling and detection technology by using machining and test tool. Using high speed milling process, though optimizing the processing programming strategy and selecting the suitable machining parameters, we could effectively solve the forming accuracy of the hyperboloid honeycomb core parts. This result showed that adopting processing and testing integrated tooling could effectively solve the problem of fixation of the weak rigidity honeycomb as well as improving the cell forming precision. After the online detection of the honeycomb core, we could use the technology of forming verification film by pre-assembling the cell part and the upper and lower skins, and the assembly tolerance between the upper and lower skins and the honeycomb part was less than 0.15mm, splicing tolerance between each separated cell was less than 0.2mm. There was no obvious difference segment in the splicing location. According to the result of verification film, honeycomb core could be fully restored to the current verification film, without tearing, damage and other defects in the forming surface of honeycomb core. It showed that its assembly accuracy meet the requirements.
