Research on Feature-based Cutting Parameters Optimization and Quality Control Technology of Blisk
Taking a blisk as a carrier,aiming at the problems of cutter relieving,vibration,deformation and so on,in the process of machining titanium alloy blisk parts of large-scale aero-engine fans,the feature-based overall blisk machining parameter optimization and quality control method research are carried out. Extracting the processing features such as blades,runners,and webs of the blisk,combined with common processing strategies such as blisk contour milling and plunge milling,a parameter optimization solution for the control of cutting force in the direction of force with weak rigidity of the feature is proposed. The relevant analysis and optimization results are in machining verification on parts. The results show that in the actual machining of parts,this feature-based blisk machining parameter optimization and quality control method have obvious effects on shortening the machining time of the blisk machining NC program,reducing the maximum cutting force,and meeting the requirements of dimensional accuracy.
