An inverse method is presented for estimating shear stress in the work material in the region of chip–tool contact along the rake face of the tool during orthogonal machining. The method is motivated by a model of heat generation in the chip, which is based on a two-zone contact model for friction along the rake face, and an estimate of the steady-state flow of heat into the cutting tool. Given an experimentally determined discrete set of steady-state temperature measurements along the rake face of the tool, it is shown how to estimate the corresponding shear stress distribution on the rake face, even when no friction model is specified.

估计加工中的剪切应力的逆方法。

提出了一种逆向方法，用于估计在正交加工过程中，沿切屑刀的前刀面切屑与刀具接触的区域中的工作材料中的剪切应力。该方法受切屑中热量产生模型的启发，该模型基于沿前刀面的摩擦的两区接触模型和对进入切削刀具的稳态热流的估计。给定沿工具前刀面的实验确定的离散稳态温度测量集，即使没有指定摩擦模型，该方法也显示了如何估算前刀面的相应剪切应力分布。
