本文首先综述了飞机大尺寸测量场构建的相关进展。其次,介绍了自动化柔性扫描路径规划的研究选展。然后,列举了柔性仳测量在飞机蒙皮间隙测量、整机水平测量和数宇化预装配等方面的应用现状。最终总结得出,飞机自动化柔性大尺寸测量技术的研究对提高飞机制造过程中的质量控制具有重要的实际意义

Case study An automatic document handler(adh)was developed at the ss level. When integrated into the total system there were many new problems. The TQM Problem Solving Process was used, and many problems were solved. However. at the field readiness Test (frt) before entering production the reliability was 15X worse than acceptable O Don Clausing 1998

Ideal response Want Ideal Response to Signal -usuall straight-line function Actual response is determined by values of control factors and noise factors If noise factors are suppressed early, the en difficult problems only appear late Introduce noises early C Don Clausing 1998

Failure modes Noises lead to failure modes(Fm) One set of noise values leads to fm Opposite set of noise values leads to FM Simple problem solving chases the problem from Fm, to Fm, and back again but does not avoid both fms with the same set of design values-endless cycles of build/test/fIx(B/T/F) C Don Clausing 1998 6.881
