This article is devoted to determining the rational range of cutting speeds during longitudinal finish turning of heat-resistant steel 20MnMoNi5-5 based on a set of tribological and vibration parameters of the cutting process. Turning workpieces with diameters D=120 mm made of 20MnMoNi5-5 steel with T15K6 carbide plates without cooling at finishing feeds and allowance values at cutting speeds of 100-220 m/min was carried out and studied. It was experimentally established that the local minimum for vibration energy was located within the speed range of 190-220 m/min. According to the results of tool life tests in this speed range, the wear rate of the cutting inserts was also minimized and the operating time of the tool was increased, making it possible to ensure the required surface roughness Ra≤1.6 μm.
