Exploiting the fact that the shape of a wire saw in contact with a workpiece (and thus being engaged in the cutting process) approximates the shape of the workpiece itself, a framework for analysing the process of wire saw rock cutting is proposed herein. The concept of rope angle is introduced to allow each bead to be configured with different magnitudes of friction, enabling estimation of the possible deformation of the resulting workpiece. The beads are assumed to be rigid; therefore, the problem of bead wear is not considered. The findings obtained from a physical experiment performed in a controlled laboratory environment are presented, wherein a driving pulley is instrumented to monitor the feed force and speed. To implement the theory in practice, predictions are made using the proposed framework to replicate the experiment. The results suggest that the friction at the bead–workpiece interface was on the order of 10 N—approximately 1% of the machine feed force. This work provides a novel model for a better understanding of the cutting process.

利用线锯与工件接触（并因此参与切割过程）的形状近似于工件本身的形状这一事实，本文提出了一种用于分析线锯岩石切割过程的框架。引入钢丝绳角度的概念是为了使每个焊道配置成具有不同的摩擦大小，从而能够估计最终工件的可能变形。珠子被认为是刚性的。因此，没有考虑胎圈磨损的问题。介绍了在受控实验室环境中进行的物理实验所获得的发现，其中装有驱动皮带轮以监控进给力和速度。为了在实践中实施该理论，使用提出的框架进行了预测以复制实验。结果表明，胎圈与工件界面的摩擦约为10 N，约为机器进给力的​​1％。这项工作为更好地了解切割过程提供了一个新颖的模型。
