This article discusses approaches to solving problem of automation of details technological design qualitative assessment, based on formalized representation of empirical recommendations. Developed principles of formal representation and use of empirical recommendations aimed on improving the manufacturability of details designs allow you: 1) for designer - to effectively apply the accumulated knowledge of such recommendations on the stages of product development in an environment of integrated CAD, 2) for technologist and operating professionals - to adequately and dynamically reflect the changes in technology, organization and technical conditions of the enterprise. The theoretical basis, proposed in this paper is used to implement software modules of details technological design qualitative assessment. The basic modes of operation with this automated system of different specialists (designers, technologists, field engineers) are discussed, as well as methods for their cooperation in ensuring manufacturability of details design using this automated system.
