INVESTIGATION OF THE TEMPERATURE IN THE CUTTING ZONE BY THE FINITE ELEMENT METHOD DURING TURNING

t is known that when cutting, the machining of the cutting tool turns into heat. Heat generation is one of the causes of accelerated tool wear. The purpose of this study is to use the finite element method to investigate the effect of temperature on the condition of tools in the process of cutting metal materials with turning cutters. Cutting tools made of hard alloy VK8 and high-speed steel P18 were selected for the study. VK8 alloy combines high hardness with high strength at elevated temperatures. The high thermal conductivity of this alloy is a distinctive feature of the tool, as it reduces the tendency to rapid local thermal softening. P18 steel has high wear resistance, sufficient strength and is resistant to heat. The effectiveness of the finite element method in predicting the cutting temperature and the stress state of a carbide cutting tool is shown. Knowledge of the temperature fields that arise during the cutting process is very important for the development of new technologies aimed at increasing tool life and reducing production costs. The cutting force is considered as the main type of cutting load. The temperature distribution in a carbide cutting tool is performed using the Solidworks Simulation analytical software. The model is created as a grid in Solidworks Simulation and the cutting force is set. Using this data, it is possible to determine the temperature and voltage of a component of the production process, which can include a cutting tool. Thus, the study of temperature and voltage is performed using Solidworks Simulation. The results obtained can be used to predict the service life of the cutting tool and the integrity of the workpiece.
