Abstract


Determining the cutting force is a fundamental aspect of the machining process, influencing the quality of the machined surface and the durability of the tools. As is known, machining duralumin can be difficult due to its tendency to form built up edge, which affects accuracy and surface finish. Knowing the cutting force allows adjusting the parameters of the cutting and tool geometry to achieve efficient and stable machining. By determining the cutting force, energy consumption can be reduced. In this paper, the average cutting force per tooth during milling was calculated, starting from the specific cutting force determined experimentally. The obtained results were compared with the experimental ones, which allowed the identification of correction coefficients dependent on the cutting speed.
