Description

  The present invention relates to an environmental assessment evaluation method that performs environmental assessment evaluation from 3DCAD model shape, assembly information, and attributes without using actual products, efficiently responds to design changes of 3DCAD data, and performs re-environmental assessment evaluation.

Conventionally, after the actual machine was manufactured, the actual machine was disassembled, and the materials and weights of the parts were confirmed and measured, and evaluation was performed based on these. Moreover, much time is required for the evaluation with an actual machine.
As a system, there was a method of searching and evaluating an assessment information DB based on a part number or the like from product part configuration information. In addition, commercially available systems using a 3D CAD model include systems having an LCA calculation function and a disassembly time calculation function.
JP 08-087475

  In the conventional method of disassembling the actual machine after manufacturing the actual machine and performing the environmental assessment evaluation, since actual parts are required, the cost of evaluation and the load of man-hours are large, and the number of times of performing the environmental assessment evaluation is limited. In addition, since the design changes are made after the actual parts are already manufactured, the scope of design changes is narrow in terms of product development cost and period, and it is difficult to thoroughly design environmentally conscious products.

  In addition, in the method of referring to environmental assessment information based on the part number from the part configuration information and performing the evaluation, the weight information cannot be automatically changed even if the shape of the part is changed, and the data is corrected manually. There was a need. Similarly, there are items that need to be manually set for configuration information, material information, and the like, and therefore it is difficult to perform an appropriate re-evaluation.

  In addition, commercial systems that use 3D models include systems that have an LCA calculation function and a dismantling time calculation function, but only a calculation function for some of the product environmental assessment evaluation items that are the subject of this study. Also, 3D CAD updates cannot be automatically reflected in the system.

  In the present invention, 3D model shape information and its assembly position, method, material information, processing information, and used number are taken from 3D CAD in units of products or units without using an actual machine. Search the environmental assessment information database from, and import the environmental assessment information. Next, the information acquired from the CAD and the information acquired from the environmental assessment information DB are aggregated and evaluated based on the logic for each component type, and the result is created as an environmental assessment evaluation report. Also, the contents of these evaluation reports can be displayed on the screen, referred to as electronic data, and printed.

  Further, by executing the above-mentioned 3D CAD to taking in environmental assessment information at the same time every day, it is possible to refer to the environmental assessment information of the product / unit in the latest 3D CAD model state at any time. Thereby, it is possible to perform the latest environmental assessment evaluation at any time.

  Also, environmental assessment information for each product / unit can be saved, and if the evaluation is rejected, some values of the saved environmental assessment information can be edited and re-evaluated. .

  It is possible to recommend environmentally conscious product design by reflecting the material, number of used items, method of use, assembly method, etc. of the parts for which the evaluation is “possible” in the design before manufacturing the actual part.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 2 is a block diagram showing an example of an apparatus for implementing an environmental assessment evaluation system based on a 3D model. In FIG. 2, PC1 is a 3D CAD input device, and the 3D CAD information is stored in the 3D CAD data server of SV1 on the network. PC2, PC3, and PC4 are data conversion processing PCs. SV2 is a product information data server, and SV3 is a product shape data server, which stores data conversion processing results. SV4 is an environmental information data server that stores environmental information data for each material information. PC5 and PC6 are PCs for product assessment evaluation and are equipped with browser software. These are connected by a network, and the printing apparatus PR1 exists on the network.

  FIG. 1 shows the flow of processing of the environmental assessment evaluation system based on the 3D model in the above configuration. S1, S2, and S3 are data conversion processing steps. In S1, information such as shape, configuration, material, and processing is referred to from 3D CAD data. In S2, the environmental information is referred from the environmental information database from the material information referred in S1. In S3, the information referred to in S1 and S2 is totaled for each product and unit for environmental assessment evaluation, and the totalization result report is stored for each product and unit in the product information database. S4 to S10 are environmental assessment evaluation steps. In S4, the environmental assessment tabulation result report stored in S3 is referred to by product or unit. In S5, the parameters in the environmental assessment tabulation result report referred to in S4 are recalculated or judged according to the environmental assessment evaluation logic to create an environmental assessment evaluation result report. In S6, it is determined whether the environmental assessment evaluation is completed. If the environmental assessment evaluation is completed, in S7, the environmental assessment evaluation result report created in S5 is linked to the evaluation target product or unit and stored in the product information database. In S8, it is checked whether or not the parts and assemblies in the product are updated by 3D CAD, and if the 3D CAD model is not updated, the environmental assessment evaluation process is terminated. If it is determined in S6 that the environmental assessment evaluation is not completed, the environmental assessment tabulation result is edited in S9 to determine whether or not to perform an environmental assessment evaluation trial. If it is determined that no further evaluation trials are to be performed, the process proceeds to a step of storing the current environmental assessment evaluation result in S7. If it is determined that an evaluation trial is to be performed, the current environmental assessment tabulation result sheet is edited in S10, and the process proceeds to the step of creating an environmental assessment evaluation result in S5.

  FIG. 3 shows a flowchart of processing for controlling the data conversion processing of S1, S2, and S3 of FIG. The process of FIG. 3 is executed by the PC 2 of FIG.
