Modelling the volume swept by a tool as it moves from one programmed position to another in the polar coordinates machining is a challenging task. In this paper, a technique for generating the volume swept by a toroidal cutter in its motion along a given tool path, is presented. This technique is based on identifying “generating curves” along the path and connecting them into a solid model of the...
The generation of curves is always an important research and application topic in the fields of computer graphics, CAD/CAM and image processing. In this study, we present a new generation algorithm for cubic curves. This algorithm is of double-step incremental type and obeys simple recurrence formulae. Furthermore, it is simple, easy to use and is suited to hardware implementation. This algorithm...
