摘要
借鉴统计学理论,将6-sigma稳健性设计方法引入工艺研发过程,探索管理学理论与民用飞机制造工艺研发相结合设计与优化的新方法,并在传统工艺基础上开展材料与工艺的匹配性研究,最后通过生产验证,该方法获得的工艺稳定,有效解决了某新型铝合金材料化学铣切表面质量问题。以化铣后表面粗糙度和晶粒末端腐蚀为响应值进行试验设计,确定影响化铣表面质量的主要因素是铝离子、氢氧化钠、络合剂和添加剂。综合单/双因素试验和RSM中心复合试验结果,新型铝合金可以采用化铣加工工艺,得出了一个较为合适的工艺参数范围。经验证,在参数范围内调节化学铣切参数,新型铝合金粗糙度和晶粒末端腐蚀参数均符合工艺工程应用的要求。
Draw statistical theory,the 6-sigma robust design method introduces technology development process.Explore management theory and the development of new civil aircraft manufacturing process design and optimization approach combined.And carry out the traditional process based on matching research materials and processes,and finally through the production validation process of the method to obtain a stable,effective solution to a new chemical milling of aluminum alloy surface quality problems.Chemical milling after the end of the surface roughness and grain corrosion test designed to respond to the value,to determine the main factors affecting the quality of the surface is milled aluminum ion,sodium hydroxide,complexing agents and additives.Integrated single/two-factor central composite experimental and RSM results,new aluminum chemical milling process can be used,reached a more appropriate process parameters. Validated,within the parameters regulating chemical milling parameters,the new aluminum corrosion parameters of roughness and grain ends meet requirements of process engineering applications.
