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 the adjustable range of a three-dimensional inter-process model, which includes (1) processing and forming a product according to needs, and making a process structure tree; (2) selecting a process that needs to be adjusted; (3) comparing the processes traversed upwards The relationship between the inter-process model and the current inter-process model, if it is a mutual interference relationship, output the node number of the traversed inter-process model, if there is no mutual interference relationship, continue to traverse until the first process of the process sequence; (4) compare to The relationship between the traversed inter-process model and the current inter-process model, if it is a mutual interference relationship, output the node number of the traversed inter-process model, if there is no mutual interference relationship, continue to traverse until the last process of the process sequence; ( 5) Output the range of model sequence adjustment between processes. The invention solves the problem that the modification of the existing three-dimensional design cannot realize the determination of the adjustable range of the inter-process model, and completes the auxiliary work for the modification of the process.
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 reviews 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 change process, uncontrollable process change process and i...
