Abstract
This paper considers mathematical modeling of the cutting process with parallel knives. It has been found that when designing the cutting process, it is important to factor into the influence of cutting forces on the mechanical properties of steel of the strip being cut, the shape and dimensions of cutting tools, as well as the process conditions, to get more accurate calculations, determine optimal cutting parameters and select cutting tools to improve performance and the quality of the cutting process. The research results contributed to reducing the discrepancy between the calculated and experimental values of cutting forces by 30% as compared with a series of experiments using the Korolev technique. The paper presents experimental data on determining cutting coefficient . The method proposed for determining the cutting coefficient is one of the methods for studying metal cutting. It is based on cutting wedge-shaped sheet samples with inclined knives. This method is used to obtain data on the geometric parameters of the cutting zone and increase accuracy of calculating the forces of cutting with inclined knives. Accuracy of determining the cutting coefficient is an important factor in cutting mechanics to calculate the required parameters of the cutting mode to achieve maximum efficiency and minimal loss of the material and time. In addition, cutting wedge-shaped sheet samples with inclined knives is useful, when testing new materials or developing new tools for cutting metals.
