Analysis of Morphology of Kerfs of Submerged Abrasive Water Jet

Abstract

Abstract:

This paper mainly focued on analysing the kerf of submerged abrasive water jet cutting from which a width of the constant region was obversed. The author adopted the Hurst index and R/S analytical method to analyse and get the temporal correlation and random in the formation of the kerf, which randomness increases and correlation deteriorates as the feed rate decreases. 

Key words: submerged abrasive water jet, kerf, width, stripe

摘要：

分析研究了淹没磨料水射流对花岗岩切割所成的切缝,发现淹没状况下切缝断面存在一宽度常数区;利用Hurst指数和R/S分析法得出了切缝形成过程中的时间相关性与随机性,得出切缝底部不仅存在时间相关性,且随着进给速度的减小,随机性增强、相关性减弱的结论。
