Technologies Realization of Direct Slicing on CAD Model in SLS
The existing RP(rapid prototyping) related software include a CAD module, a data processing module, and a monitoring and controlling module, which are independent of one another. Aiming at the issues above, this thesis picks-up the interior topological and geometrical information of model expressed in the boundary representation (B-Rep) using the development tools of ObjectARX and MDT(Mechanical Desktop) API offered by Autodesk Inc, based on a close research of the interior representation of CAD model. Direct slicing drive in CAD model is achieved. Considering the SLS(Selected Laser Sintering) technological characteristics, multi-parameter optimization is achieved by experiments, and a matching rule between scanning velocity and laser power is established so as to realize the laser power matching in different scanning velocities. In the meantime, a NC system scheme for rapid prototyping machine is designed for the SLS technology. The work of this thesis lays a solid foundation for the integration of CAD, CAPP and RP.
