The cutting force calculation model for flat grinding based on the removed metal speed and volume balance

Cutting modes in the automated mechanical engineering are still assigned manually due to the lack of modules in the CAM systems responsible for calculating the optimal cutting and testing modes to ensure satisfying the requirements of a drawing. As a result, production is facing a decrease in productivity and an increase in the number of defects and costs. One of the main reasons for deterioration in these parameters lies in the missing wide-range analytical model that establishes relationship between the cutting force and the machining modes and conditions. In this regard, design and development of a force model becomes an urgent task. The paper proposes an engineering model of the cutting force that reflects relationship between the cutting force and not only the main operation parameters, but also the abrasive grain micro-cutting parameters of the grinding wheel. The research resulted in two independent methods in developing a wide-range analytical model to calculate the cutting force based on the example of surface grinding. These models are establishing the relationship between the cutting force and the grain micro-cutting parameters, as well as the wheel cutting modes in general.
