摘要

不符合管理和持续改进的系统方法是质量管理体系的关键要素。本文的目的是通过几种统计方法和质量控制技术的结合,为生产锻件的制造公司提供质量改进。首先,应用了帕累托分析,然后是8D(八个学科)方法,使用结构化的八步骤方法来解决问题,遵循PDCA(计划-执行-检查-行动)方法。其目的是通过修改和组合适当的质量管理方法和工具,识别问题并发现导致问题发生的管理体系失效的关键原因。本文介绍了一个案例研究,考虑齿轮箱生产中的锻造过程,在去年发现了客户投诉,要求消除故障的需要。通过上述方法,发现了问题的根本原因,并根据8D报告的建议计划和实施了永久性纠正措施,从而降低了该问题再次发生的可能性,提高了客户满意度。

Quality Improvement of the Forging Process Using Pareto Analysis and 8D Methodology in Automotive Manufacturing: A Case Study
A systematic approach to nonconformity management and continuous improvements are the key elements of the quality management system. The objective of this paper is to present quality improvement for a manufacturing company producing forgings through the combination of several statistical methods and quality control techniques. First, Pareto analysis was applied, followed by the 8D (eight disciplines) methodology using a structured eight-step approach to problem solving following the PDCA (plan-do-check-act) method. The aim was to identify the problem and discover the critical causes of failures in the management system that allowed the problem to occur, by modifying and combining appropriate quality management methods and tools. The paper introduces a case study considering the forging process in the production of gearboxes, where customer complaints were identified in the last year, demanding the need to eliminate failures. Using the mentioned methods, the root cause of the problem was identified and permanent corrective action was planned and implemented according to the recommendations of the 8D report, which made it possible to reduce the likelihood of a recurrence of this problem and increase customer satisfaction.
