Abstract

In this paper we present a sheet metal Numerical Control (NC) simulation tool for cutting and punching processes, considering the internal representation of the sheet metal as a 2D complex polygon. The nature of the involved processes in the cutting and punching operations supports the utilisation of Boolean Operations between 2D polygons with fully established geometrical methods. However, straightforward utilisation of such Boolean Operations to support the material re- moval process leads to slow simulation times, since complexity of the sheet increases continuously. Some optimizations have been introduced to outperform the simulation times, such as the spatial subdivision and optimized methods to generate directly the swept area in arc movements. Results show that those optimizations are signi cant and have a direct impact in the simulation performance.
