Research On Production Process Optimization Of R Company Based On Six Sigma

In this paper,Six Sigma theory is applied to the actual case of process improvement.In this study,case study and comparative study,R Fiber Company is taken as the case study object,and DMAIC five-stage analysis model is used.This will affect the technological problems existing in R Fiber Production by Plato.The main factors of qualified rate of products are analyzed by brainstorming and tabulation,and the optimum process parameters are determined by DOE test method for quality improvement.Define the scope of the project,through the measurement,analysis,improvement,control of each step,using theory and practice combined with a clear description of the Six Sigma DMIC method in the application of fiber production process.Case study shows that there are six technical problems in R company's optical fiber production,that is,the geometric size exceeds the standard value,the quality of coating is poor,the arrangement of optical fibers is bad,the intensity of optical fibers is not up to the standard,and the PMD index is over the standard.Through the analysis of the product quality data in April 2016,the above six problems are found.The two outstanding problems are the poor coating quality and the poor geometric performance.In view of the above two key problems,DMAIC mode analysis is carried out in this paper.The main factors that lead to geometric size problems are fiber coatings,UV curing system,fiber rubbing device.The problems of UV curing system,insufficient mold cleanliness and glue overflow are solved in eight steps.The poor quality of coating is defined.The reasons are instability of test instruments,defective preform,imperfect process control system and unsatisfactory workshop cleanliness.The above problems are also solved in seven steps.According to the statistics in July,it is found that the scrap ratio of abnormal coating and bare fiber diameter has been decreased in varying degrees,and the total scrap per month has been reduced.The direct gain of the company is about 1.2 million yuan per month.This result also confirms that the application of Six Sigma Management in R company's optical fiber production process has achieved the expected economic results.It is concluded that the application of Six Sigma needs the support and full participation of the leadership,the optimization of the organizational structure and personnel system,the establishment of a sound project performance appraisal system,and the synchronization of enterprise quality culture.The innovation of this paper lies in the application of Six Sigma Management to the optimization of production process of optical fiber enterprises for the first time,especially the carding,transformation and optimization of the production process system of optical fiber products with the help of Six Sigma theory,and the proposed new business process system of optical fiber products.
