This part of ISO 10303 specifies the interpretation of the integrated resources to satisfy requirements for machining feature use across a range of application protocols. The product data is based on existing part designs that have their shapes represented by machining features. This part of ISO 10303supports digital representation for computer integrated manufacturing. The following are within the scope of this part of ISO 10303: — features that are to be manufactured by either milling or turning processes; — machining features for defining shapes necessary for manufacturing; NOTE The machining feature set is defined in ISO 10303-224. — machining feature definition elements necessary for creating machining features; — shape representations necessary for creating machining features; — features that can be replicated in patterns; — implicit representation of machining features through selection of standard parameters. The following are outside the scope of this part of ISO 10303:— feature order or sequence; — design features of a part.
