摘　　要：使用不饱和聚酯树脂、V型定位槽和定位模具制成8×8方形光纤阵列(多芯)。采用四角加压固定研磨方法进行研磨,探究了方形光纤阵列(多芯)的表面粗糙度和表面最大高度差与研磨转速和研磨压力之间的关系。结果表明,当研磨转速是12 rpm,研磨压力为2 kPa时,方形光纤阵列(多芯)表面状态最适宜,此时Ra等于10 nm、表面最大高度差为5.5μm。研磨压力对于表面粗糙度和最大高度差均有影响,而研磨转速对表面最大高度差无明显影响。An 8×8 square fiber array(multicore)was fabricated by using unsaturated polyester resin,V-shaped positioning grooves and positioning molds.Grinding was performed by using a four-corner pressure fixation method to investigate the relationship between the surface roughness and the maximμm surface height difference of the square fiber array(multicore)with grinding speed and grinding pressure.The results indicated that the surface condition of the square fiber array(multicore)was most suitable when the grinding speed was 12 rpm and the grinding pressure was 2 kPa,with Ra was 10 nm and a maxim surface height difference of 5.5μm.Grinding pressure had an impact on both surface roughness and maxim height difference,while grinding speed had no significant effect on the maxim surface height difference.
