Research on the Computer Integrated Quality System for Product Design Process

Aiming at the fact that there is no computer integrated quality system for quality control in product design phase, a data management model of design quality based on quality characteristics (QCs) is proposed, and based on this model an integrated quality control system suitable for product design phase is developed. Firstly, the content of QCs is defined and its key function in the process of product design quality control is emphasized, and the concept of design quality data is declared and the mapping relationships of product QCs and design quality data are given. Secondly, the data management model of design quality based on QCs is proposed, which is consistent with the standard of product data management (PDM). Finally, a computer Integrated Quality System for Design Process (DP-CIQS) is developed, the validity and effectiveness of DP-CIQS is verified via a preliminary application.
