Simulation and experimental research of digital manufacturing based on reverse engineering

Abstract

Reverse innovative design has long been an important subject in the engineering field. In this paper, two different-curved desk lamp stands were studied. The point cloud data of the stands was collected by using Win3D scanner and Geomagic Wrap software. Then, after facial processing of the data, reverse innovation of the facial data was performed through the reverse design software of Geomagic Design X to develop a new desk lamp stand that can satisfy engineering applications. It is actually an upgrading of the appearance of the original desk lamp stand. Finally, the numerical control program of the new desk lamp stand was completed through the processing module of UG software, and the program was verified by simulation and was used for experimental sample machining. Experimental results showed that the difference between the processed sample and the research model was less than 0.02 mm, indicating that the new design can satisfy engineering requirements and replace the original desk lamp stand. This means that reverse design technology is highly compatible with machining technology, which can shorten the innovative design period of product.
