| description |
The article analyzes the influence of the morphology of graphite inclusions and the physical and mechanical properties of cast irons on the temperature and force conditions in the cutting zone during blade processing. The features of machining gray cast iron (GI), cast iron with vermicular graphite (CVG), and high-strength cast iron with spheroidal graphite (HSG), which are widely used in machine elements operating under high thermomechanical loads, are considered. A comparative analysis of cutting temperatures and force components for GC, VCG, and HCG is performed based on experimental and modeled data presented in scientific studies.
It has been established that SG is characterized by increased hardness and reduced thermal conductivity, which complicates heat dissipation, contributes to local overheating of the cutting zone, and intensifies tool wear. It has been shown that with an increase in cutting speed, feed rate, and machining depth, there is an increase in temperature and cutting forces, especially under dry machining conditions. FEM modeling confirmed the effectiveness of this approach for predicting the stress-strain state, but requires consideration of cutting edge wear and real heat transfer conditions to improve accuracy.
Particular attention is paid to evaluating the effectiveness of modern cooling technologies. In particular, the use of the ScCO₂-MQL system allows to significantly reduce the temperature in the cutting zone, stabilize the process, and increase tool stability during high-speed milling of cast iron with vermicular graphite. |
