本文介绍了一项实验活动的初步结果,该活动旨在绘制在用锋利的刀具进行的划痕试验中切削力与切割深度的关系。在贝里亚砂岩和印第安纳州石灰岩中进行的试验证实,力随切割深度的变化取决于切割制度。它们还显示出切削力频率分布的性质与失效模式的相关性。
This paper presents preliminary results of an experimental campaign aimed at mapping the dependence of the cutting force on the depth of cut in scratch tests performed with a sharp cutter. Tests conducted in Berea sandstone and Indiana limestone confirm that the scaling of the force with the depth of cut depends on the cutting regime. They also show a dependence of the nature of the frequency distribution of the cutting force on the modes of failure.
