Facing the urgent requirement of high-precision manufacturing of carbon fiber reflective surfaces,an efficient trimming method for anisotropic carbon fiber composites was proposed.By controlling the processing time and optimizing the process parameters,the flat and curved reflective surfaces are processed respectively test.The removal efficiency and removal stability of different surface shapes by processing parameters,such as pressure,rotational speed and feed speed were explored.After multiple iterative processing,the initial surface shape accuracy of theΦ1.4m carbon fiber composite antenna reflector was converged from 21.5μm to 12.9μm,and the initial surface shape accuracy of the 1m melon reflective surface of the carbon fiber composite material converges from 17.6μm to 3.0μm,which realizes the high-precision trimming of the carbon fiber composite material,which proves the feasibility and effectiveness of the surface trimming method.
