The purpose of this research is to perform a comparative study by considering two different types of finite element models (FEM) in order to predict the output cutting regimes i.e. main cutting force and cutting temperature in machining operation. Further, these developed models are compared with the experimental data as well. A two-dimensional FEM model has been made by assuming plain strain condition to cut down the simulation cost. The finite element-based model has been developed by taking coupled temperature distribution with two different types of the position of reinforcing particle (SiC) in the Al7075 matrix i.e. uniform and zigzag. For material modeling purposes in ABAQUS software, the Johnson cook damage and evolution model has been used by varying feed rates under orthogonal cutting conditions. It is depicted from the results that model prediction errors for main cutting force (F_c) and cutting temperature (T_t) are 12.9 and 12% respectively for uniformly distributed particulates. Further, these prediction error values in the case of zigzag distribution of particulates values are 11.2% and 5.7% for F_c and T_t respectively. Results depicted from the comparison that the experimental results are in fair agreement with the developed FEM model values, however, Al7075 composite with zigzag SiC particle distribution gives improved results in terms of precision. The obtained models can predict machining output values with fair accuracy and these can be utilized to increase the machining database at low cost for industrial use.

本研究的目的是通过考虑两种不同类型的有限元模型（FEM）进行比较研究，以便预测加工过程中的输出切削方式，即主切削力和切削温度。此外，还将这些开发的模型与实验数据进行比较。通过假设纯应变条件来建立二维有限元模型，以降低仿真成本。通过基于温度分布与Al7075基体中两种不同类型的增强颗粒（SiC）位置即均匀分布和之字形的耦合温度分布，开发了基于有限元的模型。为了在ABAQUS软件中进行材料建模，已通过在正交切削条件下改变进给速度来使用Johnson Cook损伤和演化模型。对于均匀分布的颗粒，_c）和切割温度（T _t）分别为12.9和12％。此外，在颗粒呈锯齿形分布的情况下，这些预测误差值对于F _c和T _t分别为11.2％和5.7％。通过比较可知，实验结果与有限元模型值完全吻合，但是，具有锯齿形SiC颗粒分布的Al7075复合材料在精度方面提供了改进的结果。所获得的模型可以以相当的准确度预测加工输出值，并且可以利用这些模型以低成本为工业用途增加加工数据库。
