The article shows the results of various process fluids used in production and alternative environmentally friendly options on the durability of cutting tools during the milling process. In addition, the influence of the running-in process on the wear resistance of the cutting tool was taken into account. Considering the process of cylindrical milling with counter feed, dependencies were obtained based on the analysis of the horizontal component of the cutting force to find optimal running-in conditions. The article aims to evaluate the conditions for tool break-in when lubricating and cooling liquids of various compositions are supplied to the cutting zone to ensure tool durability. The task of constructing mathematical models of power characteristics Рh for various running-in conditions was formulated to establish a functional relationship between the variable and horizontal cutting force for various running-in conditions. The influence of coolant on the strengthening and formation of wear-resistant structures has been established, providing an almost 4-fold reduction in the wear rate of the tool concerning predetermined structures formed in the air. It is shown that the running-in of a cutting tool depends on the environment in which it occurs. Based on the data analysis, practical recommendations were determined for the selection of compositions of cutting fluids and running-in modes for specific milling conditions when processing AISI 321 stainless steel with subsequent transition to production cutting modes.
