Finite element analysis has become an indispensable tool, often used in research and development, to provide valuable insights into the process. The studies in the metal cutting area mostly employ the Finite element method (FEM) due to its ability to highlight the physics involved in chip formation and the range of force generated in the cutting zone. The study involves investigations by adopting the Johnson-Cook (JC) constitutive model with energy-based damage criteria to simulate the turning of a fabricated AM (Mg alloy: 7 wt%Al-0.9 wt%Mn) alloy. For the FEM, the JC and Damage model constants are calculated using inverse identification methodology. The results obtained on the cutting force (F_c), cutting temperature (T_c), and chip-thickness (t_c) at different combinations of turning parameters were analyzed and compared with the experimental values. The Predicted data was in line with the experimental data, and a variation of mostly less than 12% was observed. Thus, establishing the efficacy of inverse identification method. Further, the obtained results exhibit the significant influence of turning parameters on F_c(N), T_c(°C), and t_c(mm) and enunciates crucial facts related to the AM alloy's machinability.

有限元分析已成为不可或缺的工具，经常用于研发中，以提供对过程的宝贵见解。金属切削领域的研究主要采用有限元方法（FEM），因为它能够突出切屑形成的物理原理以及在切削区域中产生的力的范围。该研究涉及通过采用基于能量的损伤准则的Johnson-Cook（JC）本构模型来进行模拟，以模拟已制成的AM（Mg合金：7 wt％Al-0.9 wt％Mn）合金的车削。对于FEM，使用逆识别方法计算JC和损伤模型常数。切削力（F _c），切削温度（T _c）和切屑厚度（t _{c）的结果}）在不同的转弯参数组合下进行了分析，并与实验值进行了比较。预测数据与实验数据一致，观察到的变化大部分小于12％。这样，建立了逆向识别方法的功效。此外，获得的结果显示出车削参数对F _c（N），T _c（°C）和t _c（mm）的显着影响，并阐明了与AM合金可切削性有关的关键事实。
