The Research Of Reverse Engineering Work Of Special-shaped To Achieve Technology

With modern photoelectricity measuring technology and computer technology apply in a wide range of industrial,it's a hot spot in CAD/CAM area to realize the product by reverse-design and advanced manufacturing technology.The reverse engineering is the advanced manufacturing technologies of existing product's design,development and innovation.This thesis study the reverse-design work of points what are collected, processing data and analysis measure system accuracy.Analyse the contact and non-contact measurement method according to the now measuring technology qualification and the development of the situation at home and abroad,the measured work of the point cloud data acquisition using high precision and stable of Ruishilaika laser tracking instrument LeicaLTD706 + Leica laser Scanner (T-Scan)scan the work surface.The parts of point cloud data denoise;curved face mesh, fitting analysis to build work CAD model through the CATIA mechanical software what DSE,GSD,QSR processing modular As a mean to manufacture the product by the reverse engineering,we can scan and measure to make out the CAD model what domestic and foreign advanced equipment,It offer a way to absorb advanced technologies at home and abroad that accelerate development of science and technology.
