Abstract

Abstract: Due to lightweight,miniaturization and other needs of head-mounted smart glasses,polymer materials are gradually introduced into the application,but due to factors such as mold accuracy and material shrinkage during the injection process,it is easy to cause the problem of mismatch between the 3D model of the spare parts and the real thing,which causes the size of the five-axis laser linkage cutting glasses parts to be out of line. In order to solve this problem, the dimensional error between the three-dimensional model of injection products and the real objects is analyzed with the help of ATOS optical scanner. Through reverse engineering modeling of injection product parts,it verifies the feasibility of extracting the tool path trajectory for five-axis laser cutting on the three-dimensional model generated by scanning, which provides a solution to improve the precision of 5-axis laser cutting for products that do not match the three-dimensional model and the injection molding size.

Key words: size mismatch, ATOS, reverse engineering, five-axis laser cutting
