<P>PROBLEM TO BE SOLVED: To provide an efficient and accurate technique for designing an electrode shape for an EDM (Electrical Discharge Machining) process. <P>SOLUTION: A computer readable storage medium includes executable instructions to obtain an orbital path shape. Each point on the orbital path shape represents a displacement of the tool shape when the tool shape is moved along the orbital path shape. The tool shape, when moved along the orbital path shape, sweeps out a desired cavity shape. The executable instructions further include instructions to obtain an input solid model corresponding to the desired cavity shape to be swept out and derive a set of faces for a solid model of the tool shape based on the orbital path shape and a set of faces, a set of edges and a set of vertices corresponding to the input solid model. The executable instructions further include instructions to combine a subset of the set of faces derived for the solid model of the tool shape to generate the solid model of the tool shape. In one embodiment, the tool shape corresponds to a Minkowski decomposition of the input solid model with respect to the orbital path shape. <P>COPYRIGHT: (C)2010,JPO&INPIT |
