Intelligent manufacturing method driven by rational tolerance design

Abstract

The present invention provides an intelligent manufacturing method driven by rational tolerance design. The intelligent manufacturing method comprises the steps of determining key physical parameters capable of effectively reflecting corresponding product quality for a manufactured target product, and establishing a corresponding optimization model; verifying the optimization model; determining critical dimensions and non-critical dimensions which influence the product quality; establishing a multiple discipline optimization problem, respectively optimizing the critical dimensions and the non-critical dimensions, and generating an optimization result; and adjusting manufacturing processes of the critical dimensions and the non-critical dimensions according to the optimization result. According to the intelligent manufacturing method, first, the relation model of the product quality and the dimensions is established, critical factors and non-critical factors which influence the product quality can be effectively determined through determining the critical dimensions and the non-critical dimensions which influence the product quality, so that the product quality and cost can be targetedly controlled.

Description

technical field [0001] The invention relates to product manufacturing, in particular to an intelligent manufacturing method driven by rational tolerance design. Background technique [0002] In the process of product manufacturing, the manufacturing quality and manufacturing cost of the product are extremely critical. Product quality directly affects product brand; product manufacturing cost is the key to product competition and directly affects product efficiency. The manufacturing quality and manufacturing cost of the product are a pair of contradictions that are difficult to reconcile. [0003] In the past manufacturing system, due to the lack of analysis of key factors affecting product quality, product quality was often guaranteed by comprehensively improving manufacturing accuracy, which would greatly increase manufacturing costs. On the other hand, due to the lack of analysis of non-critical factors affecting product quality, in order to reduce manufacturing costs, ...

The manufacturing quality and manufacturing cost of the product are a pair of contradictions that are difficult to reconcile.

[0003] In the past manufacturing system, due to the lack of analysis of key factors affecting product quality, product quality was often ensured by comprehensively improving manufacturing accuracy, which would greatly increase manufacturing costs

On the other hand, due to the lack of analysis of non-critical factors that affect product quality, in order to reduce manufacturing costs, manufacturing precision has to be reduced across the board, resulting in a significant reduction in product quality

How to solve the contradiction between manufacturing quality and manufacturing cost lacks a systematic method
