The paper deals with the principle and structured programming of a microcomputer numerical control (MNC) system that is used on nc machining the turbineimpeller with 5-dimension interpolation.
In this article we simplify turbine supercharger impeller as a model, which was jointed of axial symmetry entity elements and plane shell elements, for finite elements analysis (FEA).
