【摘要】 作为一种新型的冷态高能束切割技术,磨料水射流(AWJ)以其独特的优点得以广泛应用,但其本身的技术特性使得切割质量存在不足。本文从能量角度分析了AWJ切割质量的影响因素,结合实验数据采用回归分析方法建立了AWJ切割质量与工作压力、切割速度、磨料流量的半经验模型,能够可以满足工程需要。为AWJ切割工艺参数优化选择及切割质量的评价、分析提供了理论基础。更多还原

【Abstract】 Abrasive waterjet (AWJ) cutting technology, as a new cold high-energy beam process, has been widely used for its considerable advantages over traditional techniques. However, there are usually some deficiencies in surface finish for its particular technical properties. In this paper, the influencing factors of its cutting quality were analyzed based on energy approach. Moreover, a semi-empirical parametric model of AWJ cutting quality with jet pressure, cutting speed and abrasive flow rate was established using regression analysis of experimental results. The error range of the model can satisfy practical needs, and can be applied to parametric optimizing selection, evaluation and analysis of AWJ cutting quality.更多还原
