3D Finite Element Modeling of Turning Processes of Metals and Composites

用于进行试验性机械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)模型，并使用在FE软件中创建的有限元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，有限元仿真可以提供**更多的洞察力，以了解在**切割过程中，工件和刀具中的加工变量发生了什么变化，这是使用实验无法实现的。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**旨在利用通用和多功能ABAQUS软件包实现上述主要目标。

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.
