一、汽车制造业中对产品的质量控制汽车制造业属于典型的大批量生产机械行业,随着现代质量理念的渐入人心和质量意识的不断加强,无论是在现代化的整车厂、动力总成厂还是零部件厂,统计过程控制(SPC)和统计抽样检验都已成为企业实施质量控制的基础。事实上,现代企业中不少产品的质量特性值甚至完全可以由工艺来保证,充其量只需辅以频次很低的抽检,以验证工艺的稳定性。这种情况在质量特性值为某些物理量时更为突出,考量一组以过盈配合方式装
First, the automotive manufacturing industry, product quality control Automotive manufacturing industry is a typical high-volume production machinery industry, with the growing popularity of modern quality ideas and the continuous improvement of quality awareness, both in the modern vehicle plant, the total power Into the plant or parts factory, statistical process control (SPC) and statistical sampling tests have become the basis for the implementation of quality control. In fact, the quality characteristics of many products in modern enterprises can even be completely guaranteed by the process, at best supplemented by very low frequency sampling to verify the stability of the process. This situation is more prominent in the quality characteristics of some physical quantities, consider a group with interference fit
