[0029] Embodiment 1

[0030] Figure 1 As shown in the flowchart of a product cost calculation method provided by Embodiment 1 of the present invention, this embodiment is applicable to the situation of calculating the product cost according to the design model during the product design stage. This method can be executed by a product cost calculation device, which can be implemented in the form of hardware and / or software and is generally configured in a computer or processor with data processing functions. As Figure 1 shown, this method includes:

[0031] S110. Determine multiple product processing information according to the three-dimensional design model input by the user.

[0032] Optionally, this method can be configured in the Product Lifecycle Management System (PLM) in the form of a plugin. The user can call this plugin in the product lifecycle management system to implement the calculation of the product cost. It can also be implemented in multiple forms such as a system or a web page, which is not limited herein. After calling the plugin, system or web page, a cost calculation page can be obtained. The user can interact with the cost calculation page to obtain the final cost calculation result.

[0033] Optionally, the three-dimensional design model is a digital model based on computer technology, which accurately describes the appearance, structure and features of the product through three-dimensional space. The three-dimensional design model can be a CAD model.

[0034] Optionally, in the cost calculation page, multiple function bars can be divided, and different contents are displayed in each function bar to interact with the user in different forms. The cost calculation page can include a three-dimensional model call bar, and the user can open the three-dimensional design model of the product in the three-dimensional model call bar.

[0035] The advantage of such a setting is that especially for the discrete manufacturing industry, the products are not mass-produced, and there may be no historical data to support the cost calculation. By calculating the product cost based on the three-dimensional design model in the design stage, it can help designers control costs in the design stage, reduce product costs and improve efficiency at the same time.

[0036] Among them, the product processing information includes material attributes, virtual factory and process route.

[0037] Among them, determining multiple product processing information according to the three-dimensional design model input by the user may include:

[0038] Extract multiple key processing features according to the three-dimensional design model input by the user; among them, the key processing features include material attributes;

[0039] Input each key processing feature into a pre-established business model to obtain at least one virtual factory output by the business model and at least one process route corresponding to each virtual factory respectively.

[0040] Optionally, after obtaining the 3D design model input by the user, the 3D design model can be automatically extracted to obtain product processing information, which includes but is not limited to geometric features, complexity, material properties, dimensions, weight, and tolerance accuracy.

[0041] Optionally, the virtual factory can refer to the processing and manufacturing factories designated by the enterprise. For example, each parts supplier of the enterprise. Each factory can have at least one process route. The process route can refer to the processing plan and rules of the product. The process route includes each process of product processing, the processing content of each process, the equipment used, process parameters, processing time, and quality requirements, etc. For example, for a mechanical part, the process route may include multiple processes such as blanking, rough machining, finish machining, heat treatment, and surface treatment. Each process has clear process parameters and operation requirements.

[0042] Figure 2 It is an example diagram of an optional process route. Figure 2 Taking the process route of piston products as an example, as Figure 2 shown, in a feasible process route for piston product processing, the processes include blanking, drilling, rough turning, finish turning, and warehousing. Among them, requirements such as processing content, equipment used, and process parameters are given for drilling, rough turning, and finish turning respectively. The specific requirements of each process can be determined according to the actual product and manufacturing requirements, and it is not limited to what requirements must be given for each process.

In the process route engine, production capacity information in each virtual factory and process route rules of each process route in each virtual factory can be pre-configured. The production capacity information can include equipment feasibility limitations, material feasibility rules, maximum processing capacity, etc. of the virtual factory.

[0044] Optionally, after inputting the key processing features into the business model, the business model can screen out each process route that can produce the product and the virtual factories to which each process route belongs according to the production capacity information of each virtual factory and the process route rules of each process route. Different virtual factories can have process routes with the same processes, and the process routes with the same processes in different virtual factories can be distinguished by different identifiers.

The user can select production plan configuration information according to the options provided by each configuration item. The production plan configuration column may further include a production volume configuration item, and the production volume configuration item is a filling item. The user can fill in the estimated production volume and production years of the product in the production volume configuration item.

[0047] Among them, the production plan configuration items include a material configuration item, a virtual factory configuration item, and a process route configuration item.

[0052] Among them, the production plan configuration column further includes a production volume configuration item, and the production volume configuration item is a filling item.

[0053] Optionally, after determining the material attributes and the virtual factory, each material attribute and each virtual factory can be configured as an optional option. Since there is a corresponding relationship between the virtual factory and the process route, at least one process route corresponding to each virtual factory is determined as a candidate option group. When the user selects a target virtual factory, the candidate option group corresponding to the target virtual factory is called in the process route configuration item to provide the process routes that can be selected by the target virtual factory for the user to further select the route.

[0054] Optionally, the business model is also configured with basic rate information of each virtual factory and information such as material utilization rate, optional processing equipment, processing time required, energy consumption analysis, tooling and die analysis, etc. of each process route. Evaluation rules are pre-loaded in the business model. According to the above information, the evaluation rules can analyze the process route, determine the process route with recommended value and the virtual factory to which the process route belongs, and pre-display the recommended process route and virtual factory in the virtual factory configuration item and the process route configuration item as a user prompt; similarly, the evaluation rules can also evaluate the material attributes according to information such as physical properties, material specifications, and material dimensions of each material, determine the recommended items of the material attributes, and pre-display the recommended items of the material attributes.

If the user needs to change the option, they can click the icon after the configuration item to obtain other optional options. Figure 3 It is intended to show the page structure form of a cost calculation page. The main purpose is to display that the page has different function bars, and no specific limitations are imposed on the specific text descriptions, icon representations, etc. in the page. Therefore, when viewing Figure 3 it, it is only necessary to clearly determine the approximate positions and structures of each function bar.
