An increase in labor productivity is realized due to a sharp increase in cutting speeds and requirements for the operability of the tool used. This requires fundamentally new solutions in the design of machine tools and cutting tools, the use of more efficient tool materials, etc. One of the ways to increase the service characteristics of the tools used is to apply wear-resistant coatings with special properties to their working surfaces. The use of wear-resistant coatings is of particular importance in conditions of modern intensification of production. There are many methods that can significantly improve the performance of the cutting tool. A special place among them is occupied by the ion-plasma method, which is implemented on vacuum installations equipped with electric arc evaporators of the metal, which is the basis of the coating. Coating a tool with this method is quite common, including due to a number of positive properties: the purity of the coating composition (due to work in a vacuum); non-toxicity of the method; the possibility of using the coating as a decorative one. The article discusses the problem of improving the quality and efficiency of the automated control system for the installation of ion-plasma coating on metal-cutting tools. Existing installations use fairly outdated and imperfect controls. In addition, existing control systems model only certain stages of the coating process. Most often, the problem of the distribution of heat fluxes in static in a tool to be heated is considered, but the problem of radial distribution of the temperature field is not solved. In this paper, the use of the Butkovsky method to simplify the solution of the problem of controlling the heating process of a tool is proposed. A general mathematical model of the dynamics of all components of the technology is proposed (tool cleaning, coating and tool cooling). Based on mathematical models, process control systems have been created.
