A system for integrating design and manufacture of centrifugal compressor by CAD/CAM is established which includes blade design

machining coordinates transformation

blade profilling in arbitrary section

checking coordinate calculation.Especially

a set of design and calculation methods is provided for manufacturing turbomachines by four-axis numerically controlled machining center.The integration system can be used on microcomputer.The system has been applied successfully to designing and machining centrifugal compressors in a factory.It is proven that the system is practical

flexible

reliable and it can cut down the time of design and manufacture with high quality.
