Online published on 27 September, 2019. Abstract The most critical component in any centrifugal compressors is impeller. Impellers are the rotating devices designed to alter the flow and/or pressure of liquids, gases, and vapors. In industries, design and manufacturing of Impeller is very difficult because of their complex geometry of vanes or blades. In this project, scoop milling technology is introduced for manufacturing of 3D shrouded impeller to avoid the manufacturing difficulties. NX CAD is used for modeling the impeller. ANSYS workbench is used for static and modal analysis. MAX-PAC CAM software is used for planning of tool path and generation of the NC post-processor for manufacturing an impeller or blade. 5 axis proof machining of the 320 mm diameter shrouded 3D impeller on Chiron 5 axis CNC machine and finally inspection of impeller by using 3D coordinate measuring machine (CMM). Top Keywords NX cads, NX cam, Max pack software, 5 axis CNC machine, 3D CMM. Top | |
