Research On The Software Of Laser Three-dimensional Carving System

Laser engraving technology is a practical and new processing technology. With more and more disciplines being used into the laser processing, the applicat-ion range of laser engraving has been greatly expanded. The development of two-dimensional marking, three-dimensional inside engraving and platform components for engraving is good, but it is reported rarely that three-dimensional(3D) deep carving of complex graphics are done. In allusion to the keystone and difficulty of the deep carving system, two algorithms are put forward. With integrating the technology of 3D display, the software of 3D deep carving system is developed. The main innovation in this paper can be summarized as follows:(1) Considering the characteristics of laser engraving and the problem of 3D covering, the data structure of box body is put forward.(2) Choose Stereo Lithography(STL) format file as the object of research for 3D engraving and the interaction interface of the system.(3) Two algorithms are put forward: slice algorithm and ray algorithm. Study and validate the feasibility of algorithm model. Considering actual conditions, the time complexity and space complexity of algorithms are optimized.(4) Based on MFC, with OpenGL technology, the laser 3D engraving software is developed. Study and optimize the user experience.(5) Adopting 3D deep carving equipment self-developed by our laboratory, build the 3D carving platform. Experiment on the aluminum material, stone material and so on.In the end of the paper, several 3D carving instances based on different materials are given. And some views and suggestions about further study are proposed.
