摘要

本文研究了磨料水射流对变质岩大理岩的侵蚀作用。研究了磨料颗粒在侵蚀过程中的破碎现象。给出了切割过程中最重要的参数如横移速度、喷嘴内径和磨料质量流量对最大切割深度的影响。为了建立侵蚀过程的数理统计模型，采用响应面(RSM)方法对侵蚀过程进行建模。采用二次多项式方程建立回归模型。研究表明，最佳的工艺参数，能达到最高的切割深度。此外，还研究了聚焦管在不同工艺条件下的冲蚀磨损。

EXPERIMENTAL RESEARCH INTO MARBLE CUTTING BY ABRASIVE WATER JET

The article presents research on the erosion of the metamorphic rock - marble by the Abrasive Water Jet (AWJ). The fragmentation of abrasive grains during the erosion process is demonstrated. The effect of the cutting process's most important parameters as traverse speed, nozzle ID, and abrasive mass flow rate, on the maximum cutting depth, is shown. To create a mathematical-statistic model of the erosion process, the methodology of the response surface (RSM) was used for modeling. The polynomial equation of the second degree is chosen for developing the regression model. Studies have shown the optimal parameters of the process, to reach the highest depth of the cut. Additionally, the erosion wear of a focusing tube under different process conditions is presented.
