Techniques for accelerating B-rep based parallel machining simulation

Continued progress in the area of solid modeller based machining process simulation is hindered by the complexity growth that occurs for a large number of tool-paths, n. For this reason, many researchers have adopted the Z-buffer approach. Boundary-representation (B-rep), however, remains the dominant choice for commercial computer aided design and manufacturing software. In this paper, it is shown that, under practical 2 1/2 D machining …
