Embodiment Construction
[0042] A method for determining the adjustable range of a three-dimensional inter-process model, comprising the following content:
[0043] 1: Classify the feature relationship; 2: Classify the model relationship between processes; 3: Determine the relationship between models between processes; 4: Determine the adjustable range of models between processes;
[0044] According to the above, the feature relationship is classified. According to the relationship between the features, the present invention can be divided into an association relationship and a parallel relationship according to whether they affect mutual processing; the feature processing process on the model between the two processes of the association relationship can be divided into before and after. , the feature processing process on the model between two parallel processes has no distinction between before and after.
[0045] Such as Figure 7 The process structure tree shown contains 8 features, which are: sq...

The invention discloses a method for determining adjustable ranges of three-dimensional inter-process models. The method includes (1), manufacturing technological structure trees according to productsrequired to be machined and formed; (2), selecting processes required to be adjusted; (3), comparing relations between upwardly traversed inter-process models and current inter-process models, outputting the numbers of nodes of the traversed inter-process models if the relations are mutual interference relations, and continuing to traverse inter-process models until first processes of process sequences if the mutual interference relations do not exist; (4), comparing relations between downwardly traversed inter-process models and the current inter-process models, outputting the numbers of nodes of the traversed inter-process models if the relations are mutual interference relations, and continuing to traverse inter-process models until last processes of the process sequences if the mutualinterference relations do not exist; (5), outputting the sequential adjustment ranges of the inter-process models. The method has the advantages that the problem of incapability of determining existing adjustable ranges of existing inter-process models by the aid of existing three-dimensional design change can be solved by the aid of the method, and auxiliary work can be accomplished for technological change.
Description
technical field [0001] The invention relates to a method for determining the adjustable range of a model between three-dimensional processes, and belongs to the field of three-dimensional process design. Background technique [0002] In the field of two-dimensional process design, process changes in production mainly adopt the change mode of two-dimensional process cards. Such a change mode is relatively cumbersome. First, the craftsman issues a change order, and the person in charge of the process proofreads and approves it; then, the process data archive department makes the change order effective; secondly, the craftsman changes the process specification according to the issued change order; Then the archives department will issue the changed process documents; finally, the process documents will use the changed state to guide production from now on. Such a model has many disadvantages, such as incomplete process of process change, uncontrollable process of process chang...
