仪器加工,例如电视机或收音机加工可分为三大工序:部件加工、底板加工、仪器装配。每道工序中都可能出现误差。因此,在部件加工中已设立了检验岗位。在底板加工和装配工序中也有检验岗位。可是,在现代化的大批量生产中,这些检验岗不足以保证质量。它们虽然可挑出废品,却不能排除 Instrument processing, such as television or radio processing can be divided into three major processes: parts processing, floor processing, equipment assembly. There may be errors in every process. Therefore, in the parts processing has set up inspection posts. In the floor processing and assembly processes also have inspection posts. However, in modern mass production, these inspection posts are not sufficient for quality assurance. Although they can pick out the waste, they can not be ruled out
