Abstract

In order to provide a usable blade model for special machining software of a blade,a parametric blade design software is developed based on the features.According to the characteristic of a turbine blade,the blade is divided into five master features:blade-root,root-surface,blade-coronal,coronal-surface and blade-body,while blade-body is divided into four child features:surface of back arc,circular arc surface of stream coming in,surface of inner arc and circular arc surface of stream coming out.3D model of the turbine blade based on features can be generated automatically by the system with blade parameters input by users.The results of machining simulation show that different cutting speeds and cutting steps can be given for different parts of the blade-body and overcut can be avoided.The paramatic blade model based on features can provide a practical base model for a blade machining software.
