摘要：通过对结构件整体镗孔工艺系统进行分析，找出刀具磨损较快的原因。设计新的连接头，调整切削参数，在保证生产效率的前提下，减少了刀具的损坏，为公司节约了成本。%In this paper,we find out the reason for the tool wearing too fast through analysis of the structures boring process sys-tem. On the premise of guarantee the production efficiency, we design a new connection and adjust cutting parameters, reduce the damage to the cutter, save the cost for the company.
摘要：The thesis analyzes the design and assembly difficulty with two aspects in details. It proposes the corresponding solu-tion from the perspective of practical production,combined with special structure and technical requirements. It sums up the suit-able assembly process and adjustment scheme, and also accumulated valuable assembling experience for the type of gas turbine.%针对M701DA型燃气轮机的总装台位设计和装配难点两方面进行了详细分析，从实际生产角度出发，结合机组特殊结构和技术要求，提出了相应的解决方案，总结出适合该机型机组的装配流程和调整方案，为该类型燃气轮机的装配积累了宝贵经验。
