Popis: Abrasive slurry jet (ASJ)-cutting technology is widely used in metal forming field. In this process, the stress of ASJ on the metal surface is a very important parameter because it directly determines whether ASJ can effectively cut metal and how the metal failure. Stainless steel is a widely used metal, and it is also a typical plastic metal material. In this paper, stainless steel was selected as the researched material to study the stress of ASJ-cutting metal. Combining theoretical analysis, numerical simulation, and preliminary experimental verification. The study results show that in the cutting process of ASJ, the stress on the surface of stainless steel is mainly caused by abrasive particles. And this stress can be obtained by theoretical deduction. The mathematical model of cutting process was built and the calculation formula of impact stress was given, the scope of application of this model was also discussed. Besides, the corresponding numerical model was established and numerical simulation was carried out. Finally, the correctness of theoretical analysis and numerical model was verified by experiment. This model can preliminarily predict cutting stress through jet and material parameters. So, it can be used to guide the setting and adjustment of waterjet parameters in industry. It has important theoretical significance and application value.
