中文摘要:
      通过磨料水射流和在磨料水射流中加入不同浓度高分子添加剂切割大理石的对比实验,测量了在不同工况下切缝表面不同位置测点的粗糙度。试验结果表明:在相同工况下,高分子添加剂磨料水射流较磨料水射流能减小切缝表面粗糙度,提高切缝表面质量;不同浓度高分子添加剂磨料射流对切缝表面粗糙度影响不一,存在最优浓度为3×10-4;磨料水射流切割中,走刀速度过慢和过快时获得切缝表面最小表面粗糙度的靶距较正常走刀速度大;高分子添加剂磨料射流切割中,不同走刀速度下获得切缝最小表面粗糙度的靶距趋向一致。 
英文摘要:
      By the cutting marble contrast experiment between abrasive water jet and high polymeric additives added at different concentration of abrasive water jet, the surface roughness of the kerf in the different station was measured under different working conditions. The experiment result shows that high polymeric additives abrasive water jet can reduce the cutting seam surface roughness than abrasive water jet under same working condition, and the quality of cutting seam surface is improved. The high polymeric additive with different concentration has different influence on surface roughness, and the optimal concentration is 3×10-4 in this experiment. When the feeding speed is too slow or too fast in abrasive water jet cutting, the target distance for the minimum surface roughness is smaller than that of normal feeding speed. The target distance for the minimum surface roughness is consistent in high polymeric additives abrasive water jet cutting in different feeding speed.
