Paper Abstract

Quality data collection information management and process control are the three key points of quality assurance in manufacturing. A kind of masterslave microcomputer network is designed to achieve plantwide quality control . The three key problems can be solved by using the hierarchical quality control method. The level I performs the data collection and supervisory control of processes. The level 2 performs higher level nonreal time functions such as data display quality reporting quality information management etc. The level 3 performs the highest level functions such as quality planning calculation of quality cost decisionmaking. As an example this system is used in the quality assurance of the final internal centerless grinding process of the internal bearing ring.
