Analyses of the influence of different polishing parameters on the surface roughness of polished silicon carbide-carbon fiber composite materials
In order to investigates the influence of polishing parameters on the surface quality of silicon carbide-carbon fiber composite materials during magnetorheological finishing,a magnetorheological elastomer method was employed for surface polishing.The effects of magnetic pole distribution,machining gap,and magnetic pole rotational speed on surface morphology and roughness were studied.The results show that the magnetic pole arrangement significantly influences the magnetic field distribution on the processed surface,thus affecting the surface quality.An increase in the machining gap leads to an initial rise and subsequent fall in surface roughness reduction,with optimal surface quality achieved at a 2 mm gap.Additionally,an increase in magnetic pole rotational speed initially heightens and then lessens the decrease in surface roughness,with the best surface quality obtained at a speed of 800 r/min.
