The problem of increasing the efficiency of processing processes and improving the quality of products can be solved successfully by the creation and implementation of methods and systems for controlling the quality of production processes. The implementation of such methods is especially important for instrument making, where in many cases the requirements for improving the accuracy of processing are of paramount importance. Analyzing the factors influencing the quality of the final product of mechanical processing [1, 2, 3], it should be noted that this is a set of indicators produced by the consumer market of products, formulated by quality standards.The rather superficial view of these indicators is to see the impact of equipment wear on their variations over time. The fluidity of the machine's parameters is especially felt on the exact parameters of the parts manufactured. Hence, the quality parameter most exposed is the size of individual fragments of the part. The more precisely it is necessary to perform this or that part size, the greater the requirements for the accuracy of the machine. But due to the rapid wear and tear of the machine tool there are possibilities of violation of the above indicators. The main factor affecting this indicator is obvious hysteresis in the movement of the forward and reverse coordinates (duality - clearance). Analyzing the work of modern CNC-machines [4, 5, 6], it is necessary to notice the fact that despite the high precision of the motion of the working surface and the tool, the machine as a forming device is technologically unlocked in its circle. The movement of the working surfaces of the machine tool and the cutting tool can occur even without the presence of a detail on the workdesktop. Such a lack of feedback leaves the technological information system in relation to the accuracy of the size be performed, the wear of the tool, the fidelity of the chosen mode of operation, th[...]
