WebbPouring even more water to sand results in a decrease of the hardness and a subsequent increase of the friction. This inverse correlation between hardness of a wetted granular material and its frictional response to sliding is found to be due to ploughing of the sledge. Webb20 sep. 2006 · This paper discusses the effects of ploughing and friction in microscale machining. The friction coefficient has previously been shown to be sensitive to the geometry of the abrasive particle and the depth of indentation. From a micromachining standpoint, the friction coefficient is modeled to be a function of the tool edge radius …
