The effect of different methods of accounting error components of the engineering system on the treatment process to achieve the desired product quality is considered. The feasibility of the inherited and operational characteristic control based on the intelligent control systems is described. The technique of the part squareness estimate is offered. The novelty of the approach is in analyzing the effect of the combined characteristics that is more informative versus the effect estimate of each of them. An algorithm for the function calculation program of distributing the cutterpath coordinates used to evaluate entering the acceptable range is presented. An example of the probable error calculation procedure application including the effect of deviation of the tool actual trajectory from the CNC programmed one under part cutting on the multi-operation machine is provided.

In terms of the conceptual approach to the intelligent electronic documentation of mechatronic technological objects, the recommendations on the knowledge system database construction are given. The requirements with which databases of the intelligent electronic documentation of mechatronic objects shall comply are described, and the utilization of the relevant standards including S1000D is proved. An example of the database creation included in the knowledge system for improving the technological object performance quality is considered. The database structure and content are described. The structure of a database XML-document by the example of the multifunction processing center is given, and its nodes are described. A fragment of the database XML-document created in accordance with the above mentioned structure is illustrated. The database performance of the multifunction processing center is designed on the basis on the presented approach.
