Аннотация: 

The machining of various steels rarely dispenses with the use of cutting operations and is inextricably linked to the cutting tool used. The operations of forming holes in steel billets are widespread in the practice of mechanical engineering. Problems of analysis and research of the cutting processes of various structural materials and cutting tools in order to obtain surfaces with specified accuracy and roughness parameters will always be relevant. When performing a cutting operation when machining a hole, up to 70% (sometimes more) of processing time is taken up by setting, which includes fixing the workpiece, tool, verifying their relative position and adjusting cutting conditions. With that, the cutting process itself takes significantly less time. This combination is an important factor in reducing the time it takes to complete an operation and ultimately reducing its cost. One of the ways to solve these problems can be the use of an easily reconfigurable cutting tool, and equipping its cutting part with a hard alloy will increase both its versatility with respect to possible processed materials and its durability. The article discusses the cutting geometry of a single-point mill. Based on the analysis of the geometry of the cutting part of the tool, factors affecting tool life were identified, a numerical experiment was made to evaluate cutting forces for recommended cutting conditions when machining low-carbon ordinary quality steels and alloyed chromium steels. Recommendations are given on the formation of sharpening angles of the cutting edges of a tool equipped with a hard alloy.
