The current research work presents, methodology of Reverse Engineering technique using portable laser arm scanner and necessary design software. A case study of Reverse Engineering using laser arm scanner and CAD tool is presented considering a typical part which is machined on CNC mill from the given CAD model. The processes in reverse engineering technique, right from object digitization, CAD model reconstruction and error analysis (Deviation Analysis) are discussed. The reverse engineered CAD model was built using Non-Uniform Rational B-splines modeling techniques and error analysis was performed comparing the data points vis-a-vis with CAD points. The results manifested that the methodology generated low error CAD models that are suitable for future engineering development using computational simulation.

Keywords: Reverse engineering, freeform surfaces, deviation analysis.
