Industrial Defects Reduction Using Quality Control Tools

Abstract

AbstractHuman-machine interface is an important contributing factor in increasing the productivity of the organization. There are various parameters which are affecting this factor and quality is one of them. Quality is an important factor in the manufacturing industry in order to raise its profit. Quality tools are one of the methods used to control and improve productivity by many ways such as reducing the repetitive mistakes. This study is about to apply the quality tools in the processing line in order to identify where the major defects occurred and to give suggestions for reduction of the concerned major defects involved in the processing line. This research is done by participating in a project in the production unit of the Suzuki Power-Train India Limited. For this, analysis of production lines such as soft and hard line of transmission system is done and the major defects occurring in these processes are identified with the help of various quality tools, such as Check Sheet, Histograms, Pareto Charts, and Cause and Effect Diagram. After this suggestions are made to reduce these industrial defects. By successful implementation of these suggestions, the rejection rates reduced from 0.044 to 0.0087% in soft line and from 0.042 to 0.0038% in hard line.KeywordsHuman-machine interfaceQualityProductivity7 QC ToolsIndustrial Defects
