Abstract

This research proposes the methodology of Reverse Engineering to repair complex geometry components. The work contains algorithms and techniques of digitizing, assessment analyses, and surface renovation. And tool path production needed for the repair process. Using a 3D non-contact determining system, outputting higher data quality, higher resolution and smoother mesh surfaces in comparison to touch probe and laser scanners digitization is accomplished.
The developed machining strategy facilitates the creation of multi-axis tool paths for removing excess material dumped in restoration process. The projected methodology has been productively executed to repair the geometry of an aero engine component and free-from surfaced parts. With the guidance, the total repair time has been reduced and the consistency of repairing a component has been improved. By using such a cost effective and time saving methodology of maintenance, repair and creation of new elements or parts, any nation or company can improve their profit margin undauntedly.
