A whole-process quality control method for products

Abstract

The invention discloses a method for whole-process quality controlling of a product. The method comprises: according to the model of a selected product, quality information of the product with the model is collected and the quality information is inputted into a database for filing; key quality characteristic parameters Ti are determined, wherein the i is equal to 1, 2, 3, ...; the quality characteristic association relationship is determined; a model is established; simulation of the three-dimensional model is carried out and an applicability degree is verified, if the applicability meets all quality requirements of the product, production is carried out, and otherwise, determination of key quality characteristic parameters is carried out again. The demand of digital, precise, flexible, and high-efficiency transformation of the production orientation of the enterprise can be satisfied; the production design and automatic production level can be improved; the resource consumption and the production cost can be reduced; the product quality and the manufacturing efficiency improvement can be promoted; and thus the core manufacturing competence of the manufacturing enterprise can be strengthened.

Description

technical field [0001] The invention relates to the field of product quality monitoring, in particular to a method for controlling product quality throughout the process. Background technique [0002] The development and production of complex equipment has the characteristics of multiple varieties, small batches, high requirements, and high risks. Under this production mode, manufacturing enterprises, especially manufacturing workshops, need to be more flexible, flexible, and agile to respond to changing quality requirements. This makes it difficult for the traditional simplistic, paper-based quality control methods for complex equipment to fully meet the needs of complex equipment development. How to use advanced quality control methods to improve the current research and development mode of complex equipment, reduce production costs, optimize operating efficiency, improve market competitiveness, and finally realize digital manufacturing has become one of the main developme...

AI Technical Summary

Problems solved by technology

[0005] At present, the research on the digital manufacturing mode, the overall method under the digital manufacturing mode, and the multi-objective optimization of each link of the digital manufacturing system is not sufficient, so the implementation of digital manufacturing methods for enterprises has only played a point of promotion, but has not played a comprehensive promotion. From the perspective of the application of digital manufacturing methods in existing enterprises, not every enterprise that has implemented digital manufacturing can achieve ideal results. A digital manufacturing model that is suitable for the business model of the enterprise; the connotation of digital manufacturing and the goal of implementing digital manufacturing have not reached a consensus within the enterprise; the coordination and optimization of multiple digital manufacturing links involving product design, manufacturing, and production have not been achieved; Ignoring the digitalization of the bottom layer of the production workshop, not paying enough attention to the data collection and real-time monitoring of workshop production, etc.
