摘要：
According to the quality problems like trailing stripe, kerf taper and cutting tail in the abrasive water jet cutting(AWJC) processes, three experimental groups were designed under different combinations of cutting process parameters, including single-positive cutting, single half-speed-positive cutting and secondary-reverse cutting experiments based on the theory of AWJC. The mechanism of the section morphology under three different cutting modes was fully discussed, and the experimental results were deeply compared and analyzed. The results show that secondary-reverse cutting may reduce the surface roughness about 52%~85% and the kerf taper about 66%~72%, with efficient elimination of the cutting tail. Therefore, the operation, adopting the method of secondary reverse cutting may significantly improve the section surface quality of the target workpiece in AWJC. © 2019, China Mechanical Engineering Magazine Office.
