In order to achieve the above object, an embodiment of the present invention provides a method for generating a process of processing a mold part based on UG/NX, the method comprising:

s100, acquiring a part model to be processed in a UG/NX format corresponding to the part to be processed;

in the step, the specific UG/NX is UG (Unigraphics NX), which is a product engineering solution produced by Siemens PLM Software company and provides a digital modeling and verification means for the product design and processing process of users. The Unigraphics NX provides a solution verified by practice aiming at the requirements of virtual product design and process design of users and meeting various industrialization requirements. UG is also an abbreviation for user guide (user guide) and general Grammar (Universal Grammar).

This is an interactive CAD/CAM (computer aided design and computer aided manufacturing) system, which is powerful and can easily implement the construction of various complex entities and models. It is mainly based on workstation at the beginning of birth, but with the development of PC hardware and the rapid growth of individual users, the application on PC has gained rapid growth, and has become a mainstream application of three-dimensional design in the mold industry. Specifically, the model of the part to be processed in the UG/NX format corresponding to the part to be processed is obtained, the model of the part to be processed before the part to be processed and after the part to be processed is manufactured can be used as the model of the part to be processed, a new model of the part to be processed can be drawn according to the actual part to be processed and used as the model of the part to be processed, and the model does not specifically form the current model.

When the part to be machined is machined, the machining procedure of the part to be machined needs to be determined, and due to the fact that structures of different parts to be machined are diverse, and the structures of some parts to be machined are particularly complex, the machining procedure is particularly difficult to process, most people cannot complete the processing, the part model to be machined, in UG/NX format, corresponding to the part to be machined, is obtained by specifically obtaining one or more of image scanning, identification, data processing, modeling and the like according to the part to be machined, and corresponding data processing is facilitated subsequently.

Step S200, identifying machining characteristics of a part model to be machined, wherein the machining characteristics comprise peripheral plane characteristics;

in this step, since the model of the part to be machined is already provided in step S100, it is determined that the machining characteristics are to be identified, and the data are processed and analyzed according to the standard, and it should be understood that the machining characteristics herein are some characteristics that can represent different machining processes, and it should be understood that different machining characteristics may employ different machining processes, or the same machining characteristic may employ the same machining process, or different machining processes. The model of the part to be machined has peripheral plane features, it should be understood that most of the parts to be machined have the peripheral plane features, and then the corresponding model of the part to be machined also has a peripheral plane, and the characteristic data can be obtained by analyzing the data of the model of the part to be machined. It should be understood that the data analysis is performed by the model of the part to be machined to determine whether it conforms to the characteristics of the peripheral plane.

And step S300, generating a machining procedure of the part to be machined according to the identified machining characteristics.

In this step, if the machining feature is recognized, what the machining process corresponding to the machining feature is, when there are a plurality of machining processes, a process corresponding to which machining feature is to be machined first, a machining time specified for the machining process corresponding to the machining feature already, and the like are specified. It should be understood that after identifying the machining feature, the machining process corresponding to the machining feature may be determined based on the machining feature, and the time to complete the machining process may be determined, and the sequence of the machining process may be determined.

It should be understood that, here, the model of the part to be machined is set to the absolute coordinate system, so that the machining feature recognition can be rapidly performed on a plurality of different models of the part to be machined under the same standard, and the models of the different parts to be machined can be better compatible. The user can also establish a standard coordinate system according to the requirement of the user. For example, the part may be centered and moved into an absolute coordinate system by the "move tool" or "transform" function of the NX software.

It should be understood that after the machining process is obtained, machining can be performed according to the machining process, but in this case, if the part to be machined has a plurality of machining processes, in order to save machining time and improve machining efficiency, the optimal machining process scheme is obtained according to optimization of the machining processes for all the machining processes of the part to be machined. Therefore, the processing of the part to be processed can be completed quickly and efficiently.

Specifically, the method for optimizing the machining process and outputting the optimal machining process comprises the following steps: and matching the machining process with a pre-stored machining process template to recommend an optimal machining process scheme.
