本文利用二维元胞自动机（CA）模型研究了磨料水射流（AWJ）切割过程中切割前沿的发展，从而间接研究了条纹形成现象。为了计算切削前沿的形状，CA 模型使用以下输入：切削速度、AWJ 强度和材料类型。切削过程通过简化的材料去除和 AWJ 传播模型以 CA 规则的形式进行描述。这些规则包括 AWJ 侵蚀工件材料的能力，以及相反的工件材料对侵蚀过程的抵抗力。通过检查各种输入参数下切削前沿发展的趋势来验证所提出的 CA 模型。模拟结果与实验获得的趋势非常吻合，从而证实了 CA 规则的正确设置。这可以让您更好地了解 AWJ 切割机制。
In this paper, the cutting front development during abrasive water jet (AWJ) cutting is studied using a two-dimensional cellular automata (CA) model, hence the striation formation phenomenon is studied indirectly. To calculate the shape of the cutting front, the CA model uses the following inputs: cutting velocity, AWJ intensity and material type. The cutting process is described by simplified material removal and AWJ propagation models in the form of CA rules. The rules encompass AWJ ability to erode the workpiece material and, inversely, the workpiece material’s resistance to the erosion process. The proposed CA model is validated by checking the trend of the cutting front development at various input parameters. The simulation results are in good agreement with experimentally obtained trends and thus confirm the proper setup of CA rules. This gives a better insight into the AWJ cutting mechanism.
