本文采用数值模拟的方法，从微观层次上研究了浆体线切割加工的机理。针对这一问题，提出了一种新的模拟线锯切割过程的方法。采用多面体颗粒离散元法模拟了金属丝和磨粒在加工过程中的运动。通过对实验装置锯切通道的直接观察，验证了结果。所提出的数值模型适用于不同的工艺参数的影响进行了详细的研究。
In the following paper the mechanisms of the slurry-based wire sawing process at micro level are studied by numerical simulations. For the simulation a new approach in simulating the wire sawing process is presented. A discrete element method (DEM) with polyhedral particles is used to simulate the movement of the abrasive particles as well as the wire during the process. The results are verified by direct observations of the sawing channel of an experimental setup. The presented numerical model is applied for a detailed study of the influence of different process parameters.
