Research on Error Analysis and Control Method of Digital Coordination Machining of Coordination Hole of the Carrier Rocket Part
In the view of the difficulty of digital coordination of coordination hole of the carrier rocket part,the influencing factors of digital coordination processing are analyzed and the main reasons are determined,and the influence of measurement error and positioning on the machining accuracy is analyzed through comparative test and theoretical analysis.On this basis,the digital coordinated machining control scheme is put forward,and the typical part is taken as the object to carry out coordinated hole test,the test results show that the digital quantity coordination machining hole position accuracy meets the requirements of assembly coordination,and the test coordination with the tooling platform,laying the foundation for the engineering application of the end-frame digital quantity coordinated machining.
