Description

Matching method of DPA component based on flexible manufacturing Technical Field The invention belongs to the technical field of intelligent manufacturing, and particularly relates to a matching method of DPA components based on flexible manufacturing. Background Flexible manufacturing (Flexible Manufacturing) is a new production model that is created to cope with large-scale custom requirements. The method emphasizes the adaptability and flexibility of the production system, and enables the production system to rapidly respond to market demand changes, product design updating and manufacturing process changes by adopting the flexible production system and advanced technologies such as industrial Internet, artificial intelligence and the like, thereby efficiently meeting customized production demands. DPA (Destructive PHYSICAL ANALYSIS ) is one method of validating the process and process control level of a component production lot. The method aims at obtaining the whole quality information of the components of the batch by sampling from the production batch and adopting a series of nondestructive and destructive inspection and analysis means to verify whether the design, structure, material and manufacturing quality of the components meet the related specification requirements or the preset purpose. In the existing intelligent manufacturing process, the DPA detection requirements (such as detection items, sampling proportions and the like) of different customers or products on components are different. In the component matching link, the following problems mainly exist: 1. the detection requirement identification is difficult, namely, production planning or bill of materials (BOM) is difficult to intuitively and automatically identify which components need DPA detection and specific detection requirements. 2. The process has low efficiency, and because of difficult identification, the process often depends on manual judgment and coordination, so that the period of waiting for detection instructions or materials in the production line is prolonged. 3. And the delivery risk is high, DPA detection links or detection reports are easily omitted, so that the files are incomplete when the products are delivered out of the warehouse, and delivery and compliance are affected. 4. Cost accounting inaccuracy-the cost incurred by DPA testing (e.g., off-commission testing cost, sample cost) is difficult to accurately integrate into a specific part or product cost. For this reason, there is a need for an automated DPA component kit method that can be integrated into a flexible manufacturing system to solve the above-mentioned problems. Disclosure of Invention Aiming at the defects of the prior art, the invention provides the matching method of the DPA component which has reasonable design, high matching efficiency, short period and is based on flexible manufacture. The method can realize automatic identification of DPA detection requirements, intelligent matching of detection materials and accurate accounting of related cost. In order to achieve the above purpose, the present invention adopts the following technical scheme: A matching method of DPA components based on flexible manufacture is characterized by comprising the following steps, (1) Establishing DPA component requirements directory And establishing a management database for storing and managing DPA detection requirements of different components, creating directory entries for each component needing DPA detection, and recording detailed information.
