【摘要】：近年随着机械硬盘(HDD)的需求在2010年达到顶峰后呈现出负增长,而且固态硬盘技术(SSD)的逐渐成熟更是瓜分了机械硬盘业务部分市场份额,对机械硬盘行业造成了很大的冲击。如何不断地研究改进管理方式、缩减成本、提高产品质量、缩短新产品周期、提高客户的满意度和忠诚度也就成为公司保持一定的竞争优势并且不断提高公司收益的关键所在。为满足新形势下客户不断变化的,高精度、高质量的需求,企业纷纷把供应商质量管理作为其核心战略,抛弃传统的基于企业本身的质量管理思想,把企业内部以及外部之间质量形成过程当成整体过程进行质量控制和管理。目前国内外已有许多质量管理的研究成果,主要集中在企业内部的质量控制和质量保证,库存管理,供应商的评价和选择等,本文针对S公司对弹性臂现行免检入库的瓶颈—就是弹性臂关键质量特性(CTQ)精度要求高但与弹性臂供应商测试机相关性偏倚波动大容易引起供应商生产的质量特性中心值偏移目标值,本文运用六西格玛DMAIC改进流程找出影响弹性臂质量特性测试波动的主要关键要素,通过稳定测试相关性的改善和建立标准样本监控测试机制度,把现行事后处理问题的免检入库制度流程在测量系统稳定性的基础上提出基于标准样本实时监控的事前免检入库流程,有效地减少因为供应商测量系统不稳定造成不良批次流入S公司生产线,避免质量问题造成的不良分析以及返工、退货等引起质量成本增加和产品周期延长等不可估量的质量损失和市场损失。
[Abstract]:In recent years, with the demand of HDD has reached its peak in 2010, and the technology of solid state hard disk (SSDs) has matured gradually, it has divided the market share of mechanical hard disk business, which has caused a great impact on the mechanical hard disk industry. How to continuously study how to improve the management mode, reduce the cost, improve the product quality, shorten the new product cycle, improve customer satisfaction and loyalty also become the key to keep a certain competitive advantage and constantly improve the company's income. In order to meet the ever-changing, high precision and high quality demands of customers under the new situation, enterprises take supplier quality management as their core strategy one after another, and abandon the traditional quality management thought based on the enterprise itself. Take the process of quality formation within and outside the enterprise as an integral process for quality control and management. At present, there are many research achievements in quality management at home and abroad, mainly focusing on the internal quality control and quality assurance, inventory management, evaluation and selection of suppliers, etc. This paper aims at the bottleneck of S company to the flexible arm which is the key quality characteristic of the elastic arm, which is the key quality characteristic of the elastic arm. But the fluctuation of the bias associated with the supplier testing machine of the elastic arm can easily lead to the special quality of the supplier. Property center value offset target value, In this paper, we use the six Sigma DMAIC improvement process to find out the main key factors that affect the fluctuation of the elastic arm mass characteristic test, and establish the standard sample monitoring and testing machine system by improving the stability of the test correlation and establishing the standard sample monitoring and testing machine system. Based on the stability of the measurement system, this paper puts forward the pre-inspection and warehousing exemption flow based on the real-time monitoring of standard samples. Effectively reduce the flow of bad batches into S production line due to the instability of supplier measurement system, avoid bad analysis and rework caused by quality problems, Return of goods such as increased quality costs and product cycle extension such as incalculable quality loss and market losses.
