Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] Such as figure 1 As shown, a processing quality influencing factor sensitivity analysis and quality control method includes three parts: the establishment of the relationship model between processing quality and influencing factors, the sensitivity analysis of processing quality influencing factors and the processing quality stability control. In order to realize sensitivity analysis and quality control, it is first necessary to obtain the relationship model between processing quality and influencing factors. The establishment of the relationship model between processing quality and influencing factors is as follows: figure 2 shown; then through the relational model, let each influencing factor change the same percentage separately, calculate the sensitivity and contribution rate of the influencing factors, and analyze the factors that have a gr...

Abstract

The invention discloses a method for sensitivity analysis and quality control of processing quality influencing factors: (1) Establishment of a relationship model between processing quality and influencing factors, which is used to analyze the effect of influencing factors on processing quality, and provide a basis for subsequent processing quality sensitivity (2) Sensitivity analysis of processing quality influencing factors, through sensitivity analysis of the relationship model between processing quality and influencing factors, calculate sensitivity and contribution rate, and identify factors that greatly affect processing quality; (3 ) Processing quality stability control, according to the sensitivity analysis results, use the sensitivity to control the controllable influencing factors with certain rules, reduce the fluctuation of processing quality, and improve the stability of processing quality.

Description

technical field [0001] The invention belongs to the field of product quality control, and relates to a method for sensitivity analysis and quality control of processing quality influencing factors. Background technique [0002] The market share and competitiveness of products are directly determined by the quality of processing. The quality of a product is often affected by many factors. The fluctuation of processing quality is caused by several of the more important factors. The fluctuation of processing quality will directly cause economic losses. It is particularly important to find out the factors that have a great influence on the processing quality and to control the fluctuation of the processing quality. [0003] At present, the analysis methods of factors affecting product quality mainly include one-way analysis of variance, orthogonal test, correlation analysis, and sensitivity analysis. Among them, one-way analysis of variance, orthogonal test, and correlation an...
