根据对尺寸公差分析方法和工艺能力评价方法在统计学方面的理论成果,结合飞机装配中的尺寸协调准确度控制目标与控制要求,实现对航空制造的尺寸公差分配。研究了飞机数字化装配协调过程中采用基于工艺能力指数的方法评估装配尺寸的协调准确度。
According to the theoretical results of the dimensional tolerance analysis and the evaluation of the technological capability in the statistics, the size tolerances of the aircraft manufacturing are realized by combining the size control accuracy and the control requirements in the aircraft assembly. The coordination accuracy of assembly dimensions was evaluated using a method based on process capability index in the coordination of aircraft digital assembly.
