摘要
国内外常用的机械铣削方法难以加工在航空航天、军事工业及高端装备等领域应用日益广泛的高温合金、钛合金、金属基复合材料等难切削材料,存在加工效率低、刀具损耗大和成本高等突出问题。对此,国内外学者研究开发了不受被加工材料的强度和硬度等影响、具有加工效率高、成本低等优点的高速电弧铣削技术。针对国内外常见的高速电弧铣削工艺方法、加工工艺特性和材料去除机理等进行了综述分析,并简要阐述了电弧铣削技术未来的发展趋势。
Mechanical milling methods commonly used are challenging to process difficult-to-cut materials such as superalloys,titanium alloys,and metal matrix composites,which are increasingly widely used in aerospace,military industry,and high-level equipment.The main difficulties are low processing efficiency,large tool wear,and high cost.In order to solve the above problems,scholars at home and abroad have researched and developed high-speed arc milling technology.It is not affected by the strength and hardness of the processed material and has the advantages of high processing efficiency and low cost.This article summarizes commonly used arc milling methods and their processing characteristics and material removal mechanism and briefly explains the future development trend of arc milling technology.
