In this paper is considered a way to solve the problem of increasing the quality parts of marine diesel engines based on the use of functionally-oriented technologies. The study of the operating conditions details is a distinctive feature functionally-oriented technologies from the traditional. The article analyzes the conditions of the stationary parts of marine diesel engines: the base frame, the crank case, the cylinder sleeve, the cylinder top. The loads acting on the parts, component malfunction and cause of component malfunction are given. It was revealed that the most stressed parts of the core is a marine diesel cylinder sleeve. It was shown that the functionally-oriented technology can significantly improve the quality of the manufacture of parts working in severe conditions, and more fully realize the potential of the details. In the work is shown and described total object-oriented model of the structure synthesis of the functionally -oriented process of manufacturing the cylinder sleeve. The design stages of technological processes of manufacture bushings is described traditional and functionally -oriented. The synthesis stages of functionally-oriented technological process of the manufacturing the cylinder sleeve is given. Operational functions, acting on the sleeve are shown. The sleeve division process on functional elements is shown based on the depth of the division. It is indicated that in the next stage are assigned types and schemes of technological impacts. The paper notes the need to create three databases. The database No1 should contain a properties set of the sleeve functional elements, the base No2 principles, methods and techniques of technological transformation, the base No3 the scheme of technological impacts. The interaction databases is described. With the impact of technological schemes converts the product properties of the initial parameters in the final properties of the principles and methods. These design features of functionally-oriented technologies have allowed to reveal their greatest advantage. They make it possible accurate selection process influences. They allow for the view, size and shape of the functional element, the value and type of loads acting on this element. This allows more fully use the potential of parts, improve the durability and reliability.
