Creation and comparison of three-dimensional models of a mechanical part in agriculture field by forward and reverse engineering

Abstract

In the last 30 years, we often hear about the computer aided design method with the help of the developments in adapting the innovations in the field of computer to the field of design. This method is divided into two sub-methods as forward and reverse. In this study, two methods were applied and compared for a combine harvester part used in the agriculture field. In the reverse engineering method, part was scanned with the laser scanner and the resulting point clouds were made into a mesh structure. These network structures have been improved and optimized with the necessary steps. Then the solid model was created with optimized mesh. In the forward engineering method, a 1/1 scale solid model of the part was created with the help of a caliper. The accuracy analysis of the solid model created with the network model was performed and the deviations from the real values were calculated and interpreted. At the end of the study, the three-dimensional models created by both methods were compared morphologically and the results were evaluated. The average accuracy value between the two models was calculated as 98.24%.
