Abstract
This work is devoted to the study and refinement of the parametric model of the formation of surface roughness. The refinement of the available parametric model was carried out by conducting experimental studies in order to determine the optimal parameters affecting the process of roughness formation. As part of the experiment, various factors such as processing speed, tool type, initial material characteristics and others are considered in order to identify their influence on the final surface characteristics. The article describes a mathematical model with eight parameters 𝑎𝑖(𝑖=1,2,3,4) 𝑎𝑛𝑑 𝑏𝑖(𝑖=1,2,3,4), which depend on the processing conditions. An important role in the formation of surface roughness is played by the type of material of the cutting part of the tool, the cutting speed. The data that was obtained was used to assign initial parameter values for conducting a logistic analysis of Ra-V over the entire range of cutting speeds.The results of the study can be applied to optimize the processing of materials and improve the quality of the products obtained. The data provides important information for the development of more accurate and efficient models of surface roughness formation in industrial and engineering applications. The results obtained not only confirm the assumptions of the model, but also reveal additional nuances that may play a role.
