Problems solved by technology

[0002] The current process design is based on the two-dimensional model. The process design does not use the design model, and the design model does not consider the process requirements, resulting in a disconnection between the process and the design, and the information cannot be associated; and the process card is a pure text description. Simplified diagrams can only express part of the information, and multiple processes are expressed on one diagram; for NC machining, remodeling is required, and different NC machining procedures need to be modeled again, etc.

example 1

[0036] According to the process design method based on the 3D model mentioned above, the process design method of the part: step 1, open the part design model, create the part process model, select the current model, clear the memory of the manufacturing model and process model, and check the blank size parameters and offset With the rotation parameters, the software generates a process model including the design model by default. If there is an exception, adjust the parameters of the generated process model to realize that the process model and the design model form an assembly.

[0037] Step 2, choose to open the process model, implement process feature construction on the basis of the process model blank, implement feature construction on the blank according to the smooth processing, and add annotation information on the basis of each process, and add audio data annotation The information can also be a description in Chinese characters, and the label information can be added...

example 2

[0042] The process design method for components according to the process design method based on the three-dimensional model: step 1, open the component design model, select the assembly process model, select the required formwork assembly process model and design model, and generate the process model.

[0043] Step 2: Design the process rules under the assembly process model, use the right key to add process steps or use shortcut keys to add process steps, and design the process steps required for assembly components.

[0044] Step 3, right-click the model included in the process step, or use the shortcut key to include the process model of the component. The model contained in the corresponding process step is the model required for assembly and processing. The software will automatically arrange the process content in a default way , from the previous process content to superimposed in sequence, and complete all the parts required for component assembly in sequence.

Abstract

The invention discloses a technology design method based on a three-dimensional model. The method comprises the following steps of based on a design model, according to a technology condition, carrying out model adjusting and generating a three-dimensional technology model; constructing a technological procedure; in the same three-dimensional technology model, according to the technological procedure, successively carrying out different operation designs, classifying the technology models based on operation and generating a plurality of different technology design models; displaying technology information of a technology design model in a display interface, wherein technology information data is stored in a database; carrying out three-dimensional technology simulation on parts or components in the technology design model; and finally generating a technology publishing result and animations possessing an interaction interface. The three-dimensional model is used to visually and accurately describe a formation process of a product from a blank state to a final state; a problem that a traditional two-dimensional technology can not express an intermediate state of a product formation process is solved; characteristics that intuition is good and interactivity is high are possessed; technology design work efficiency is greatly increased; and an optimization degree of a technology design scheme is improved.
