Graphs of the influence of cutting speed and feed rate on the surface roughness Ra of the machined 0.12C-18Cr-10Ni-Ti steel at t = 0.05 mm Conclusions 1. Calculations have established that when modeling the machining of 0.12C-18Cr-10Ni-Ti stainless steel parts with a diameter of 10 mm using a diamond cylindrical head with a 3 mm working diameter, the maximum cutting power reached 0.128 kW, and the maximum tool deformation was 0.23 mm, with
