摘要： A method for collaborative analysis pre-processing of electronic models of engineering objects includes assigning a first user to de-feature a model of an engineering object during a first session to provide a de-featured model of an engineering object, assigning a second user to conduct other FEA pre-processing operations on the model of the engineering object during a second session, and applying the other FEA pre-processing operations for the model of the engineering object to the de-featured model of the engineering object. Example of other FEA pre-processing operations include applying a material definition to a geometry, pre-meshing a geometry, initiating automated meshing of a geometry, validating automated meshing of a geometry, editing a mesh for a geometry, manually meshing a geometry, and defining one or more boundary conditions for a geometry. The second session and the first session may be conducted concurrently. A corresponding system and apparatus are also disclosed herein.

摘要： A method for generating a toolpath includes providing a plurality of machining target models based on a model of an engineering object, assigning the machining target models to CAM clients operated by users, receiving a machining instruction sequence from each CAM client, and machining a part by executing each of the machining instruction sequences on one or more machine tools. The machining instruction sequences may be merged into a single machining instruction sequence before being executed by a machine tool. The machining target models may be created manually or automatically generated. In certain embodiments, the machining target models are generated by spatially partitioning the model of the engineering object. In one embodiment, features that are allocated to a separate machining process are removed from the machining target models. A corresponding apparatus is also disclosed herein.
摘要翻译：一种用于生成刀具路径的方法包括：基于工程对象的模型提供多个加工对象模型，将加工对象模型分配给由用户操作的CAM客户端，从每个CAM客户端接收加工指令序列，并且通过在一个或多个机床上执行每个加工指令序列。加工指令序列可以在被机床执行之前合并成单个加工指令序列。可以手动或自动生成加工对象模型。在某些实施例中，通过对工程对象的模型进行空间分割来生成加工对象模型。在一个实施例中，分配给单独加工过程的特征从加工目标模型中移除。本文还公开了相应的装置。

摘要： A multi-user CAx editing system may comprise a plurality of editing clients and a collaborative editing server. The server and editing clients may be collectively configured to: a) assign a feature to a first user, detect an attempt to edit the feature by a second user, and reassign the feature to the second user if the first user indicates that the feature may be reassigned, and/or b) detect an editing conflict between a first and second user for a feature and send a reversion request for the feature to one or more clients and/or c) initiate changes for a feature within a remote instance of the electronic model edited by another user and initiate reversion of the changes for the feature within a local instance of the electronic model in response to determining that the changes to the feature within the remote instance of the electronic model generated an error.

摘要： A multi-user CAx editing system may comprise a plurality of editing clients. The editing clients may be configured to maintain data consistency for geometric elements created within each local instance of a model of an engineering object. For example, each of the plurality of editing clients may include a synchronization module configured to identify one or more distinguishing parameters for each locally created geometric element and generate a unique persistent label for the geometric element, and communicate the unique persistent label and the distinguishing parameters to other editing clients. The communication may occur via a collaborative editing server. The other editing clients may find a geometric element within their local instance of the model that matches the distinguishing parameters and associate the unique persistent label with that geometric element. Subsequent references to the geometric element may be made by referring to the unique persistent label.
