The Application Research On Precision Machining And Measurement Technology Of Radome

Radome is one of the key parts of missile,its electrical performance directly affects the missile's accuracy.Radome has a thin revolving body of complicated surface.With the continuous improvement of the missile performance requirements,more and more highly accuracy requirements is put forward in the process of radome machining.Because of the inhomogeneity of permittivity and error of geometrical thickness,the radome's electrical thickness can not meet the design requirements.In order to further improve the machining efficiency and machining quality of radome,this paper studied the existing radome fixture installation system optimization and measurement based on the existing processing equipment.The research objectives follow as:According to the technical requirements of high performance radome,the key technologies of the radome existing processing equipment are deeply analysis.The reasons of radome processing error are concluded.Then this paper puts forward some key problem which needs to be improved based on existing processing equipment,and it provides valuable basis for further effective improvement of equipment.In view of the existing radome exterior surface and inside surface rigidity and stability of the fixture,improved the design of fixture,improved internal profile fixture.In view of the existing profile fixture in the instability of profile ring problem.This paper also made optimization design for the existing internal mounting fixture,reduced its weight and maintained its rigidity.In the conversion processes,the installation location for radome is ensured by installation system rather than the manual adjustments,greatly improve the efficiency of the radome installation.This paper had the experiment of the radome surface and exterior surface of the fixture installation error analysis,Within of the experiment,the experimental results improved the stiffness of antenna enclosure type surface fixtures,ensure the installation precision.On the basis of the existing machine tools,and puts forward the overall reconstruction scheme of radome special grinding system,According to the requirements of the radome grinding,grinding wheel,grinding and grinding wheel rack is designed which is for type within the radome surface and exterior surface of grinding.During grinding processing and compensation,the grinding force,and the grinding wheel and workpiece contact arc length are analyzed.These parameters can provide the reference when grinding CNC program are written.
