Abstract: Reliability work run through all life cycle of product. Integration of reliability information and information and of product design, technology, manufacture and use is a main part of concurrent engineering, Reliability of all-life-cycle of CNC machine tool product is analysis, and a new thinking of CNC machine tool reliability engineering for concurrent engineering is proposed. A CNC machine tools’ reliability control model for concurrent engineering is proposed and built.

Key words: All-life-cycle engineering, CNC machine tool, Concurrent engineering, Control model, Reliability
