The article is devoted to the analytical and experimental study of cutting with a single grain when grinding titanium alloy VT8 and carbon case-hardened steel 12Cr2Ni4A. Titanium has high strength, good corrosion resistance, and, at the same time, has a relatively small mass, which makes its use indispensable in areas where, along with their mass, good mechanical properties of products are essential. The machining of titanium is hampered by its very high chemical activity at elevated temperatures. A weld may form in the contact area. It changes the geometry of the cutting edge by the formed build-up. The object of the study is the unit cutting forces that occur during the grinding of titanium alloy and carbon case-hardened steel, as well as the associated values that affect the quality of the machined surface. The research used samples of titanium alloy VT8 and steel 12Cr2Ni4A. Grinding was carried out with cubic boron nitride (CBN) wheels. The results of this study will further allow the prediction of the parameters of the part processing mode to obtain the necessary indicators of the quality of the surface layer and the geometric dimensions of the part while increasing the productivity of the grinding wheel and minimizing energy costs. The study aims to establish the dependences of the change in unit cutting forces and the values emerging from them during the grinding of samples from VT8 and 12Cr2Ni4A.
