The design characteristic and effect of DMU (Digital Mock-Up) are simply introduced. According as the design characteristic of complex product, the request for DMU platform in product life cycle is analyzed, and function analysis of DMU platform is finished. The whole frame and logic configuration are illuminated based function analysis, the realization method of design validation and optimization, design cooperation, maintenance support are emphatically analyzed, and some applied examples of DMU are displayed. The future imperative studies for DMU are discussed based the developed work and existent problem.

Geometric Tolerances

Tolerance information plays a critical role in many steps of the product life cycle. It is especially important due to the advances in Internet technologies and increasing integration requirements from industry. In this paper, geometric tolerances information in manufacturing process (IMP) is studied, and the layered conformance level of geometric tolerances is established according to ASME Y14.5-1994, STEP and DMIS. An EXPRESS-G data model of geometric tolerance information in IMP is established. The XML language is used to represent and program the geometric tolerances information in IMP.
