接近零不合格过程的质量分析及控制探讨

该文对提高接近零不合格过程的质量分析和控制的准确性及效率进行探讨,提出对接近零不合格过程的质量分析首先应根据产品质量要求和过程能力要求选择合适的aσ,且要与接近零不合格过程的控制的程度相适应,然后利用传统的统计过程控翩(SPC)的方法对过程进行质量分析和控制,使过程处于受控状态或良好的受控状态,同时利用该状态时的不合格...

Discussion on Quality Analysis and Control on Near Zero-nonconformity Process

This paper discusses the improvement of accuracy and efficiency of quality analysis and quality control on near zero-nonconformity process,puts forward that quality analysis on near zero-nonconformity process should first choose an appropriate aσ according to product quality demand and process capacity demand,and the QA should be suited for the degree of near zero-nonconformity process control,then complete QA and QC on this process through traditional statistical process control（SPC） so that make the process in controlled or well controlled condition,meanwhile take fraction defective under this condition as a reference to help fulfill QA and QC on near zero-nonconformity process and eventually improve QA and QC during the whole manufacturing process.
