Embodiment

[0061] Detailed description for a certain type of radome with a depth of 1029mm

[0062] 1) Design and customize knives

[0063] In order to obtain the maximum rigidity, when simulating machining, all parts of the tool (including the tool holder, all straight shanks and all variable diameter shanks) cannot collide with the inner surface of the part, and the various parts of the tool are designed to maximize. After repeated simulations, it is preliminarily determined that The preliminary shape of cutter bar 11, promptly reducing handle has three kinds: Reducer handle 5, Reducer handle 7, There are three kinds of reducing handles 9 and straight handles: Straight handle 4, Straight handle 6, Straight shank 8, the diameter of knife bar 10 is 20mm;

[0064] 2) Determine the 0° machining coordinate system and determine the machining position

[0065] Before processing, the theoretical model of the part is used on the UG 3D software to determine the 0° machining coordina...

Abstract

A deep blind cavity machining and on-line measurement of gliding radome is disclosed. The method includes steps of designing and customizing the tool, determining the 0 DEG machining coordinate systemand determining the machining position, rotating the 0 DEG machining coordinate system and determining the machining coordinate system after the rotation X DEG, determining the machining allowance and establishing the 0 DEG machining coordinate system, and processing Cavity, using the measuring device to detect the coordinates of the typical point of the inner cavity and determining the correctedvalue by comparing the theoretical model data of the part, and finishing the inner cavity at 0 DEG and X DEG respectively. The invention solves the defect of machining the deep blind cavity of the existing gliding radome, and has high machining precision; through on-line detection to understand the real-time dynamics of parts, detection efficiency is high, and parts with accurate correction processing.

Description

technical field [0001] The invention relates to the technical field of hypersonic glide ballistic missile radome processing and measurement, in particular to a deep blind cavity processing and on-line measurement method of a glide radome. Background technique [0002] Hypersonic glide ballistic missiles have the characteristics of high strike accuracy, long range, super high speed, high penetration performance and strong anti-interference ability. In recent years, China has attached great importance to the development of this type of missile. In order to improve the missile's penetration capability, striking accuracy and anti-jamming capability, the new missile radome adopts a large number of waverider structures and composite materials. [0003] From the analysis of its working principle, after the missile re-enters the atmosphere, the primary and secondary engines are separated, and the gliding warhead has a small amount of power. The orbit is corrected in real time throug...
