Abstract:There is a high dimensional accuracy requirement for inner surface of E shaped waveguide component for rader use.Now mainly using machining to produce such parts,the material utilization ratio and productive efficiency are very low.Based on the technology of precise plastical forming,the die is designed by CAD/CAE/CAM,and precise backward extrusion process for E shaped waveguide component has been developed.The result shows that through analyzing and controlling the process parameters,defects can be avoided...
Keywords:LF21antirust aluminium  E shaped waveguide component  precise backward extrusion  process parameters
