Research on Manufacturability Evaluation Methods of Aeroengine Blade

In this paper according to the analysis of the manufacturability of aeroengine blade, the manufacturability evaluation is considered a multi-level decision problem, and manufacturability qualitative evaluation method based on production rule and manufacturability quantitative evaluation method based on AHP comprehensive evaluation are established. Due to the complexity of the latter method, the detailed solving steps of the process are present and an example is taken for explanation. Using above research methods, product design can be guided according to feedback information by evaluating the part manufacturability.
