摘要
对磨料水射流的切割质量进行了试验研究,通过改变水射流压力、切割进给速度来研究切割断面质量,对AWJ切割机理和切割过程进行了分析,探讨了AWJ切割断面的形貌特征及其形成机理,认为是射流断面磨料动能的分布不均和射流的偏转滞后造成了AWJ切割断面斜条纹和曲线及尖角处的尖端,提出了两种提高磨料水射流切割质量的方法。
Experimental study is practiced to examine AWJ cutting quality. By changing waterjet pressure and cutting speed, cutting kerf surface quality is studied. By the analysis of AWJ cutting mechanism and cutting process, the thesis explores the specific shape of the cutting section and its mechanism, and believes that the asymmetric distribution of abrasive jet' s kinetic energy and jet' s deflexion causing the formation of striations, waviness and cuspi- date end. However, high - efficient cutting of AWJ could be achieved by two designs.
