切削仿真的发展仍然需要在刀具-工件材料界面处的摩擦现象的理解的改进。本文介绍了一种快速识别摩擦和热分配模型的方法，基于一种特殊的摩擦计，能够模拟大范围的接触压力和滑动速度，类似于发生在沿着切削刀具-工件材料界面。该方法适用于广泛的工作材料和润滑条件。结合分析后处理，这种设置提供了一个模型的摩擦行为，可以显着改善切割模拟热方面。(C)2013年CIRP。
The development of cutting simulation still requires an improvement in the understanding of the frictional phenomena at the tool-work material interface. This paper introduces a method for a fast identification of friction and heat partition models, based on a special tribometer able to simulate wide ranges of contact pressures and sliding velocities, similar to those occurring along the tool-work material interface in cutting. The method is applied for a wide spectrum of work materials and lubrication conditions. Combined with an analytical post-treatment, this set-up provides a modelling of the frictional behaviour that may improve significantly thermal aspects in cutting simulations. (C) 2013 CIRP.
