Patent ID: 7885722

Claim:
A method for computer-aided generation of tool parameters for tools for the manufacture of sheet-metal forming parts by way of forming processes, wherein a representation of a manufacturing process is produced, which representation comprises a set of machining steps and geometric parameters of these machining steps, wherein the method comprises the following steps: generating, using a data processing unit, a set of geometry features ( 11 , 12 , 13 , 14 , 15 ) of a part ( 10 ) in a geometry model of the part ( 10 ), wherein each of the geometry features ( 11 , 12 , 13 , 14 , 15 ) is described by way of a feature type and by way of geometric parameters for describing the geometric shape of the geometry feature ( 11 , 12 , 13 , 14 , 15 ); generating, using a data processing unit, an associated method standard for each of the geometry features ( 11 , 12 , 13 , 14 , 15 ) by selecting a method standard from a list which associates, with each type of geometry feature, a sequence of alternate method standards, wherein a method standard is a combination of manufacturing steps that describes one variant for manufacturing the respective geometry feature ( 11 , 12 , 13 , 14 , 15 ), and the selection of the method standards which may be associated with a certain geometry feature ( 11 , 12 , 13 , 14 , 15 ) is dependent on the feature type of the geometry feature ( 11 , 12 , 13 , 14 , 15 ), and wherein a method standard comprises at least one module, and a module represents a machining unit and describes which machining unit may be executed within a forming operation; determining components for each of the modules of the method standards, wherein these components describe the parts of tools which are required for realizing the module; generating, using the data processing unit, component parameters from the geometric parameters of the geometry features ( 11 , 12 , 13 , 14 , 15 ), wherein the component parameters comprise geometric parameters of the components or of the respective tools; and producing, using the data processing unit, a representation of a manufacturing process including a series of said component parameters and a method standard.
