description: The work is devoted to the adaptation of the control system for contact operations in machining to the uncertainty of the properties of the workpiece. During the construction, the following tasks were solved: 1) Carrying out mathematical modeling of oscillatory processes during drilling and obtaining characteristic modes of stability loss. 2) An algorithm for suppressing undesirable oscillatory processes creation and investigation of its applicability for more complex models of drilling dynamics. 3) Analysis of the possibility and justification of the feasibility of using artificial neural networks and other machine learning methods to determine the optimal cutting parameters in terms of quality and performance, corresponding to the previously undefined properties of the workpiece. 4) Development of an adaptive control system based on the correction of drilling parameters using machine learning methods for chatter suppression under the condition of uncertainty of the mechanical parameters of the material. The result of the work is an adaptive control system, which efficiency has been demonstrated by a series of numerical experiments. The system obtained in this work can be improved for practical use in machining.
