The main problem of manufacturing products in conditions of flexible automated production is the achievement of high quality indicators of parts, such as accuracy characteristics, surface roughness and surface layer condition. Obtaining of high quality parts in modern technological systems requires the study of specific features of flexible production. Frequent readjustment of equipment, replacement of tools, redistribution of characteristics of the elastic system of machine tools, the production of parts from materials of different workability determine the variablenature of the accuracy parameters of products manufactured in flexible manufacturing systems (FMS). In addition, the difficulties associated with the full automation of the technological process are added: automatic basing and fixing of workpieces and tools, transfer and reorientation of parts for processing on various machine modules, accumulation of errors when basing blanks on satellites, branching of dimensional connections of multipurpose machines, inaccuracies of automatic adjustment and positioning of the tool, the need for active control of the treated surface and the condition of the cutting tools, providing feedback between real and specified accuracy, automatic maintenance of thermal characteristics of machine equipment, ensuring optimal cuttingmodes for all FMS machines. The solution of most of these problems is achieved through adaptive management of the processes in order to obtainspecified indicators of processing quality. Designing the optimal technological process under changing conditions of flexible production is a very difficult task, due to the multivariate technology of processing parts included in the group. Meanwhile,in the theory of group production there are methods to optimize the process of choosing the right technological solution. With the optimization of group technologies, it is necessary to be able to specialize in real production. On the first stage on the basis of advanced technological processes, it is necessary to create a type for the development of technological processes. The cost of developing such processes is insignificant, so that the technology is widely implemented. In the process of developing group technological processes of machining complex parts or a complex combination of surface elements of a part in order to ensure the efficiency of the process, it is necessary to solve the problem of optimizing machining parameters in accordance with accepted optimality criteria and taking into account the main technical limitations. At the same time, it is considered as the optimization of constantly set, for a specific instrumental group adjustment, processing modes using the methods of mathematical modeling and automated information processing, and continuous optimization with the help of control systems for technological equipment, which are part of the FMS. Therefore, the problem of calculating and optimizing cutting modes on interconnected FMS machines is extremely urgent. At the same time, not the most intense modes are considered optimal, but just those that ensure the stable operation of the FMS for a long time.
