摘要
磨料水射流切割工艺以其独特的"冷、软"加工特性,与其他切割工艺相比,对各类热敏、硬脆等难加工材料的切割更有独特优势,具有良好的发展前景。但因射流自身的"柔性"特征,尤其在切割大厚度材料时存在断面明显坡度、波纹、滞后、切缝、回击等质量不足,成为制约该技术应用市场推广的瓶颈。本文从磨料水射流切割工艺原理和工艺优势出发,在指出其工艺缺陷和切割效果工艺影响因素的基础上,提出针对性的关键技术,对拓展该技术的应用领域具有积极的现实意义。
Abrasive water-jet cutting process with its unique cold and soft processing characteristics, and more unique advantages compared to other cutting process according to all kinds of thermal and hard brittle materials has good prospects for future development. But because of its own flexible jet characteristics, especially in cutting big thickness materials, it exists the quality insufficient obvious such as slope, corrugated, cross section lag, cut back sewing. That becomes the mar- keting bottlenecks restricted technology. In this paper, from the abrasive water jet cutting process principle mechanism and technology advantages, based on the points out its defects and cutting process effect factors affecting process, the specific key technology was proposed. It has positive practical significance to expand the application fields.
