Damaged or broken parts are generally too expensive to replace, or no longer available. Re can be defined as ‘systematic evaluation of a product with the purpose of replication. This includes design of a new part, copy of an existing part, recovery of a damaged or broken part, development of model accuracy and inspection of a numerical model. Task is to reproducing the geometries of aero engine physical component in digitizing process through 3D scanning and complete conversion of physical data into CAD model by using modern measuring machines with its integrated software’s (creo 2.0) extractions of information about geometry to develop part models parts which have to be reverse engineered. CMM inspection and reverse engineering software are employed to evaluate any dimension deformations. Deviation in the dimension is taken in to consideration as evaluating characteristics. The error analysis of some features between 3D scan data, CMM, CAD model, and MESH data are performed.Deviation between scan data, CAD model, and CMM are within acceptable limits. And deformation between CAD model and MESH data are within -0.1 to +0.1mm. The CAD model generated is within acceptable criteria (30 microns).
