Focus of the Comparative Study
The focus of the comparative study was on enhancing the accuracy of process simulations by incorporating important factors such as latent heat and temperature-dependent properties of Inconel 718.
Inconel 718 is a nickel-based superalloy known for its high strength, corrosion resistance, and temperature stability. However, machining this material presents challenges due to its hardness and high melting point. To address these challenges, advanced machining processes such as EDM and hybrid electrical discharge and arc machining have been explored.
Latent heat and temperature-dependent properties play crucial roles in the machining of Inconel 718. Latent heat refers to the energy required for phase changes like melting or vaporization during the machining process. Temperature-dependent properties account for the variations in material properties with temperature changes.
By incorporating these factors into the models, the researchers aimed to improve the prediction of material removal, heat-affected zones, and other machining characteristics. The comparative study involved comparing simulation results with experimental data to validate the accuracy of the models.
The findings of this study have significant implications for optimizing and understanding the EDM and hybrid electrical discharge and arc machining processes on Inconel 718. Considering latent heat and temperature-dependent properties in the models can provide more realistic predictions and insights into the material behavior during machining operations. This can help in guiding process parameters, tool design, and enhancing the overall efficiency and quality of machining Inconel 718 using these advanced techniques.
