The cost and time devoted to conducting experimental machining tests (purchasing materials, inserts, and**toolholders, preparing experimental set-ups, ...) and subsequent costly, time-consuming measuring residual**stress can be eliminated by developing 3D finite element (FE) modeling of turning processes and providing a**virtual laboratory using the FE models created in the FE software. In addition, FE simulations can provide**much insight to understand what happens to the machining variables in the workpiece and tool during the**cutting process, which are not possible using experiments. This assists to control and optimize machining**characteristics such as temperature and surface integrity including residual stresses. The proposed research**aims at fulfilling the above major objectives using the general- and multi-purpose Abaqus software package.

用于进行实验性加工测试的成本和时间（购买材料、刀片和 ** 刀柄、准备实验装置等）通过开发车削过程的3D有限元（FE）建模并使用FE软件中创建的FE模型提供 ** 虚拟实验室，可以消除随后昂贵、耗时的残余应力测量。此外，有限元模拟可以提供 ** 更多的洞察力，以了解在 ** 切削过程中工件和刀具中的加工变量发生了什么，这是不可能使用实验。这有助于控制和优化加工 ** 特性，如温度和表面完整性，包括残余应力。拟议的研究 ** 旨在利用通用和多用途Abaqus软件包实现上述主要目标。
