Research on evaluation approach of feature-based part manufacturability under concurrent engineering environment

Part manufacturability under concurrent engineering (CE) environment was analyzed in detail. A system framework of design for manufacturing (DFM) was proposed according to CE ideas. An evaluation system and a definition model for feature-based part manufacturability were established. Product design can be guided according to feedback information by evaluating the part manufacturability. An example of rabbet-feature manufacturability of a turbine blade was given to show that the method is effective and available.
