Study of the influence of the design of the turning tool on the removal of thermal energy from the cutting zone

Abstract

In this work, we performed a study and developed the design of through-cutters that provide accelerated heat removal from the cutting zone with external turning. Using SolidWorks Simulation engineering analysis and SolidWorks Flow Simulation gas-hydrodynamic analysis modules as a research tool, we created a basic 3D model of a precast cutter and carried out a thermal analysis of the transition process to determine the distribution of temperature fields in the body of the cutter throughout time during the cutting process. After that, we made changes to the design of the cutter, specifically, created a cavity in the holder body in which the copper core was placed. We then re-performed the studies described above, which showed that when using a copper core, the temperature in the cutting zone decreases by 246 °C within 15 minutes from the start of the work. To obtain a greater effect, we added a hole in the copper core and used air cooling, which allowed reducing the temperature in the cutting zone by 313 °C.
