SIMULATION ANALYSIS OF STRIATION PHENOMENA IN ABRASIVE WATER JET CUTTING (AWJC) PROCESS OF AISI 304 STAINLESS STEEL

摘要

Abrasive water jet cutting (AWJC) technology has been widely used in metal processing field. However, the generation of striations deteriorates cutting quality. In this paper, Smoothed particle hydrodynamics (SPH) coupled Finite element method (FEM) is used to simulate and analyze the cutting process of AISI 304 stainless steel. The results show that the declining jet angle will result in uneven erosion of abrasive particles, which is caused by the generation of striation phenomenon. The research can deepen the understanding of striation phenomena in metal machining process.
