Measurements enabling the online monitoring of the abrasive waterjet (AWJ) cutting process are still under development. This paper presents an experimental method which can be applicable for the evaluation of the AWJ cutting quality through the measurement of forces during the cutting process. The force measuring device developed and patented by our team has been used for measurement on several metal materials. The results show the dependence of the cutting to deformation force ratio on the relative traverse speed. Thus, the force data may help with a better understanding the interaction between the abrasive jet and the material, simultaneously impacting the improvement of both the theoretical and empirical models. The advanced models could substantially improve the selection of suitable parameters for AWJ cutting, milling or turning with the desired quality of product at the end of the process. Nevertheless, it is also presented that force measurements may detect some undesired effects, e.g., not fully penetrated material and/or some product distortions. In the case of a proper designing of the measuring device, the force measurement can be applied in the online monitoring of the cutting process and its continuous control.
能够对磨料水射流(AWJ)切割过程进行在线监测的测量方法仍在开发中。本文提出了一种实验方法,该方法可通过测量切割过程中的力来评估AWJ切割质量。我们团队开发并获得专利的力测量装置已用于多种金属材料的测量。结果表明,切割力与变形力之比取决于相对横向速度。因此,力数据可能有助于更好地理解磨料射流与材料之间的相互作用,同时影响理论模型和经验模型的改进。先进的模型可以在很大程度上改善AWJ切割、铣削或车削过程中合适参数的选择,从而在过程结束时获得所需质量的产品。然而,研究还表明,力测量可能会检测到一些不良影响,例如材料未完全穿透和/或一些产品变形。如果测量装置设计得当,力测量可应用于切割过程的在线监测及其连续控制。
