The article considers introducing automated quality control systems to the industrial enterprises, which is very important today. There are many factors that negatively affect the reliability of products used in different industries (transport, agriculture, etc.). One of the important factors at present is the quality of turning parts, which, in turn, is influenced by the state of the cutting tool. Practical research shows that a greater number (35%) of cutting tool breakdowns happen due to its wear, and the time spent on changing the cutter is, on average, 10% of the working time of mechatronic machine tool systems. To prevent breakage of the cutter and damage of products associated with wear, it is necessary to determine in a timely manner the moment of the beginning of critical wear of the cutting tool. Thus, a need arose for the development of an automated system for recognizing the initial phase of critical wear of a cutter during turning on a CNC machine in real time, and it is essential to create a reliable algorithm and software and mathematical support. The implementation of the considered algorithm for determining the critical wear of the cutter in turning according to the stability margin of the dynamic system and its software implementation make it possible to use the tool resource and practically eliminate the rejects associated with late replacement of the cutter during turning, as well as significantly reduce financial costs under conditions of mass production to which the suboptimal consumption of the working resource of the tool leads. The proposed decision helps to increase the turning efficiency
