Reverse Engineering on Jet Engine Turbine Blade Based on 3D Printing Design Intent

Abstract

Reverse engineering plays a significant role in rebuilding of a product. This suggests a situation arranged for reverse engineering of turbine blade used in aero engine components. It is the process that designs by using point cloud data to get CAD models. Reverse Engineering is a method for creating CAD model of physical parts whose designs are not available or fractured or damaged parts by digitizing a persisting prototype, reverse engineering creates a computer model by applying 3D scanning. In this paper it is for reproducing the geometries of aero engine physical components i.e. turbine blade in digitizing process through 3D Scanning and CMM Inspection. Complete transformation of physical data into CAD models by applying modern measuring machines and with its integrated software (Creo 2.0) extraction of information about geometry to develop the part models. CMM inspection & reverse engineering software be located active to evaluate any dimension deformation. The deviation in the dimension is taken into attention as evaluating characteristics. The error analysis of some features between 3D scan data, CMM, CAD model and MESH data are performed. The deviation between scan data, CAD model & CMM are within the suitable limits and deformation between CAD model & MESH data are within -0.1 to +0.1mm. The CAD model generated is within suitable criteria i.e., 30 microns. Parts which require to reverse engineered. After completion of the CAD model 3D printing development is done.
