21页1、Boolean operations for 3D simulation of CNC machining of drilling tools Dani Tost*, Anna Puig, Llus Perez-VidalSoftware Department, Polytechnical University of Catalonia, Spain Accepted 25 April 2003AbstractThis paper addresses the simulation of drilling tools CNC machining. It describes a novel approach for the computation of the boundary representation of the machined tools. Machining consists of a sequence of Boolean operations of difference between the tool and the grinding wheels through ti
2、me. The proposed method performs the dynamic Boolean operations on cross sections of the tool and it reconstructs the 3Dmodel by tiling between the cross sections. The method is based on classical computational geometry algorithms such as intersection tests,hull computations, 2D Boolean operations and surface tiling. This approach is efficient and it provides user control on the resolution of the operations.Abstract This paper addresses the simulation of drilling tools CNC machining. It describe

IntroductionMost of the research on CNC in CAD is centered on theautomatic computation of tool paths 5,13. Given a final tool design, the optimal trajectories of the tool and the grinding wheels must be computed yielding as final
