This paper analyzes the advisability of using the adaptive system on the CTX gamma 2000 TC multi-operation machine to improve the processing efficiency. Since modern multi-operation machines are very expensive, it influences on the cost of machining. Therefore, it is of practical interest to develop and study adaptive control systems that improve the accuracy and productivity of machining. The combined effect of all the elementary errors of the system arising during processing is taken into account. The process of setting the cutting tool to a size is described, the expressions for the optimal tuning size are generalized. To solve the problem of minimizing the influence of these errors on the machining process, a system of adaptive control of limiting regulation was proposed. The principle of the system operation has been described and the structural scheme of the system has been given. As a regulation parameter, the cutting power was used; it being the key factor in the processing efficiency. Due to the adaptive control system, both the efficiency and accuracy of machining were improved through a decrease in depreciation deductions from the machine. The economic feasibility of using such a system was established. In the same way, a method for calculating the adjustment size has been developed, based on the accuracy of machining balance. Thus, the improvement of machine tools due to adaptive control systems of limiting regulation is an actual problem of domestic engineering. In this paper, an adaptive diagram has been drawn up, which makes it possible to compile a universal general equation of the accuracy balance of a technological operation, and to determine the calculated control system for the CTX gamma 2000 TC machineReferences
