A Study of the Hot Cutting Technology to EPS Architectural Model

Abstract:

This paper provides the details of continuous cutting technology to architectural model made by EPS. To solve the interference problem between outline surface and hot cutting-wire in the cutting process, STL model projection profile method is used. Slicing algorithm based on grouping matrix is proposed to cutting the outline model continuously. Local topological relations in each group are established to improve the efficiency of slicing cutting. In order to apply this algorithm to the actual process better, automatic programming system with Visual C + + 6.0 based on STL model is developed, which used the 5-DOF CNC thermal device to cut the model. The experiment shows that this technology can cut the outline architectural model efficiently and accurately.
