飞机制造自动制孔机械系统技术研究

摘要

The aircraft manufacturing industry ia a high technology industry which concerns the national economic lifeline. common mechanical assembly accounts for 20%of the total product of labor, while aircraft assembly accounts for 40%to 50%of the total labor, besides,quality requirements are strict and technical difficulty is much great. aircraft assembly needs a lot of complex assembly jigs and the accuracy of airplane manufacturing depends largely on the accuracy of the assembly, while that of common machinery mainly depends on the accuracy of the parts manufacturing.%飞机制造业是一个关系国家经济命脉和国防安全的高技术产业。一般机械的装配工作占产品劳动总量的20%，而飞机装配占劳动总量的40%-50%，而且质量要求高，技术难度大。飞机装配使用了许多复杂的装配型架，飞机制造的准确度很大程度上取决于装配的准确度，而一般机械主要取决于零件制造的准确度。
