摘要： A method and a corresponding system and computer program are provided. A model of an object to be manufactured via subtractive manufacturing is obtained. Geometric features to be machined as part of manufacturing the object are identified based on the model. The identified geometric features include a composite geometric feature including a plurality of geometric subfeatures. A database including strategies for machining different geometric features is accessed. The database includes a composite strategy for machining the composite geometric feature and separate strategies for machining the respective geometric subfeatures. Strategies for machining the respective geometric features are selected from the strategies included in the database. Instructions for causing one or more machine tools to manufacture the object in accordance with the selected strategies are provided. Selecting strategies for machining the respective geometric features via subtractive manufacturing includes selecting the composite strategy for machining the composite geometric feature.

摘要： A method for optimizing manufacturing data in a subtractive manufacturing system includes obtaining a model of and tolerance requirements for an object to be manufactured and performing measurements on the manufacturing system in a static condition. The method further includes simulating a manufacturing process in the manufacturing system using the obtained static information to obtain runtime information, determining which manufacturing data is responsible for producing each feature of the manufactured object, simulating manufacturing of the object, and comparing the simulated finished product of the object with the three-dimensional model of the object, detecting a deviation between the simulated finished product and the obtained tolerance requirements included in the model, and based on the detected deviation and the determination of which manufacturing data is responsible for producing each feature, optimizing the manufacturing data such that an object manufactured based on the optimized manufacturing data complies with the obtained tolerance requirements.

摘要： A method and a corresponding system and computer program product are provided. A model of an object to be manufactured is obtained. Information about one or more available machine tools and one or more available cutting tools is obtained. A geometric feature to be machined as part of manufacturing the object is identified. A database including strategies for machining different geometric features is accessed. The database includes a plurality of strategies defining different ways of machining the identified geometric feature. One or more strategies are selected from the plurality of strategies based on the obtained information. A computer simulation is performed for the one or more selected strategies, and user instructions responsive to the computer simulation are received. Instructions for causing one or more machine tools to manufacture the object via subtractive manufacturing are provided based on the user instructions and a strategy of the one or more selected strategies.
