Application of Haptics in Reverse Engineering Based on Physical Objects

Abstract

This paper through a case study presents an application procedure for haptic modeling in reverse engineering based on physical objects. Starting from the import of a dataset digitized from a physical object, by 3D touch the final digital prototype for reconstruction can be sculpted, smoothed, etc. to form a shape of interest. Afterwards, patches can be created from a fine-constructed curve framework and stitched into a final surface model. Such modeling is characterized by flexibility, creativeness and rapid efficiency, and can construct surface with fine visual effects. The study also investigates the limitations in the modeling capabilities of commercial haptic feedback technology restrict its ability to make a significant contribution to reverse engineering practice. And a future direction of fusing haptic technology into conventional reverse engineering systems is supposed as a result.
