摘要： The invention notably relates to a computer-implemented method for designing, with a CAD system, a 3D modeled object representing a mechanical part. The method comprises providing a B-rep representing the mechanical part. The B-rep has faces, edges and vertices. The method comprises providing a sharp edge. The method further comprises, automatically by the CAD system, identifying a set of edges. The set of edges comprises the provided sharp edge. Each first edge of the set of edges is directed similarly to at least one second edge of the set of edges, the first edge and the second edge sharing a face. The method further comprises, automatically by the CAD system, selecting sharp edges within the set of edges. Such a method constitutes an improved method for designing a mechanical part.

摘要： A method for developing a numerical control manufacturing program for a common geometric feature (38) of a first component (36A) includes obtaining manufacturing process data for the common geometric feature (38). The manufacturing process data is associated with one or more numerical control manufacturing processes for the common geometric feature (38) of one or more second components (36B). Each of the one or more second components (36B) includes the common geometric feature (38). The method further includes determining one or more manufacturing constraints for the numerical control manufacturing program for the common geometric feature (38) of the first component (36A), selecting a numerical control manufacturing process of the one or more numerical control manufacturing processes, obtaining manufacturing process parameters for the selected one or more numerical control manufacturing processes, and developing the numerical control manufacturing program for the common geometric feature (38) of the first component (36A). The developed numerical control manufacturing program includes the manufacturing process parameters.
