.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 b
