Abstract

Cutting is a production process commonly employed used in various industries. The aim of improving its efficiency entails the improvement of the durability of the cutting blade, increasing the accuracy in terms of the resulting item dimensions obtained after cutting, but also the quality of the obtained edge. The material factor for the above is the distribution of forces in the cutting edge and cut element system. Furthermore, the pursuit of minimized interaction of forces in this process is of significance, which has a positive impact both on the durability of the blade as well as the process energy consumption. The paper presents a simulation of the process of cutting a flat bar made of aluminium. The numerical model was built in the ABAQUS system. The model includes a knife-cut element. The purpose of performing simulation tests is to determine the cutting force, changes in its value and the nature of these changes when cutting with knives of different geometry and trajectory.
