超高压水切割多功能特征解析

Introduction and Analysis of the Ultrahigh Pressure Water Jet Cutting Multifunctional Application

航空航天对超高压水切割提出了特殊技术要求,笔者应对大尺度曲面复合材料切割,大型叶轮粗加工和特殊精细切割,复合材料的铣削、钻孔、抛光等需求,以国家863计划课题为契机,研制了500MPa压力的特大型专用机翼加工装备和多功能加工中心,本文介绍了这2台先进装备所引发的超高压水射流多功能技术特征,并结合国外同步先进水平解析了实现高难度水切割、铣削等多功能应用的技术模块、参数匹配、工艺方法和试验结果。

The aerospace industry bring a new development for ultrahigh pressure water jet cutting technology,such as large scale curved composite components cutting process engineering application,large scale impeller rough cutting,special precise cutting,composite material’s milling/drill/polishing.In a national high technology research and development plan as an opportunity,the writer develop a500MPa ultrahigh pressure machining equipment for super-huge type wing and a multifunction CNC center.This paper introduce the ultrahigh pressure water jet multifunctional technical features about these two equipments involved,and combine with the foreign development situation,analysis the technical modules/parameter match/process method/experiment result in realizing the highly-difficult water jet cutting/milling and other applications.
