| Quality professionals use the term “standards†to mean many things, such as metrics, specifications, gages, statements, categories, segments, groupings or behaviors. Management standards address the needs of organizations in training, quality auditing and quality-management systems. The global automotive industry demands world class levels of product quality, productivity and competitiveness as well as continual improvement. To achieve this goal many vehicle manufacturers company using quality control tools to improve the quality of the product with zero defects and highly satisfied to the customer. Now days, there are lot of quality tools applied to solve the problem quicker but it’s still the fact to find out good and efficient solving way.This thesis papers emphasis on identification of potential failure; failures may encountered in the production process and its will leads to car scrap, rework and influence of the internal production and quality target(defects control rate). After the complete study of manufacturing process and production data-failure causes, failure rate and data etc. FMEA discover the weak processes in the form of higher risk priority number in the manufacturing of the car painting process, which required reducing by identifying and implementing of the defects and this will improve the process quality of the painting surface of the car. To analysis the improvement of the car surface defects SPC(Statistical process control) tools are more efficient where can easily visible the defects trends.SPC chart are chronological graphs of process data that are used in manufactures industries to help understand, control and improve process and that although based in statistical theory area easy for practitioners to use and interpret.In order to orient goal of zero defects of the car surface use the PFMEA technique to prioritized the defects and statistically analysis the roots cause of the defect and control the defects through continues improvements process. |
