In this paper, we propose feature models of a machining operation and machined surface, which correspond directly to the machining process model. The feature model of the machining operation is proposed from the viewpoint of the dimension of a macro cutting tool, the dimension of feed motion, and the number of enveloping constraints. The machining feature is also proposed from the viewpoint of the removal volume (tool swept shape), machined surface (enveloping tool swept shape), and the contacting shape between the required surface and cutting edge during one cutting motion (unit-shaping element). We proposed the abstract model of the machining process and the abstract model of operation planning which could represent the linear equations. We also pointed out that there are only 15 types of machining operations.

International audienceThis chapter presents classification and representation of shape features in sheet-metal parts. Shape features in a sheet-metal part model can be associated with volume subtraction from base-sheet (e.g., piercing/blanking operation), deformation/modification of base-sheet or forming operation on base-sheet. The shape features in a sheet-metal part model are classified as (i) Volumetric features and (ii) Deformation features. These features can also be classified as ‘2-dimensional (2D) features’ (volumetric features) and ‘3-dimensional (3D) features’ (deformation features) as a result of modification and forming of base-sheet. The thickness is constant for a sheet-metal part. Hence, the shape features in a sheet-metal part are also referred as constant thickness features. The representation, classification, and extraction procedures of the sheet-metal features are based on topology and geometry. The novelty is that the proposed classification and representation of sheet-metal features is based purely on shape entities and therefore it is possible to automatically extract the features from any sheet-metal part model. This enables the use of the proposed classification and representation to be unambiguous and application independent and to handle equivalences between feature labels and their representations among applications. The definition presented for a feature can also be extended to include application specific information
