Abstract
<jats:p>The article considers the influence of selected cutting and heat treatment modes on surface residual stresses for thin and flat products made of 08Kh15N5D2T (VNS-2) steel. Introduced stresses (both residual and during cutting) can occur for many reasons, including: incorrect machining modes; insufficient rigidity of the machine-fixture-tool-part (MTP) system, introduced deformations during the manufacturing process (additional straightening of the product), deformations during cooling of the part after heat treatment and other processes occurring during manufacturing. Machining modes affect the value of the introduced residual stresses. Stresses can be in the surface layer or "inside" the product. The surface layer is largely affected by machining, and the internal layers are affected by heat treatment and the method of obtaining the workpiece. When excessive stress accumulation occurs in the surface layers of the product, their redistribution may occur, which may manifest itself in the form of residual deformations leading to irreparable defects. The article discusses the results of an experiment on samples made of steel grade 08Х15Н5Д2Т (ВНС-2), which were previously subjected to hardening, aging, end milling and flat grinding. A study of surface residual stresses was conducted. Conclusions were made based on the results obtained.</jats:p>
