Application of reverse engineering approach on a damaged mechanical part

Abstract

Reverse engineering methods are important for remodeling or measuring damaged or non-damaged parts. Reverse engineering also enables the design of complex components, reducing actual product production time and prototype production time. With this method, damaged gear wheels can be modeled in a short time due to the regular geometry and symmetrical properties of the teeth and it is real models can be produced. In this study, the damaged motor cam gear was scanned with a three dimensional (3D) scanner and a mesh model was formed. Then, solid model of part was created and genuine prototype was produced with 3D printer. The deviations of geometric dimensions between the mesh model and the solid model were analyzed and the levels of convergence were determined. The three-dimensional prototyping method provides great convenience for the designer due to it gives quick feedback in product development process. At the end of the study, geometric values between solid model and prototype model were compared and deviations from actual value were determined.
