We used microtextures to develop a novel antifriction technology for wood cutting tools. Northeast China ash (Fraxinus spp.) was selected as the research species, and the influence of the microtexture on the friction coefficient of cemented carbide samples with and without the texture was studied using various loads and wood moisture content. The results showed that a reasonable microtexture form (d = 40 μm) can effectively reduce the friction coefficient between wood and cemented carbide regardless of the moisture content. The moisture in the wood is conducive to reducing the friction coefficient between the cemented carbide and the wood surface. Its mechanism of action is affected by the wood moisture content, the load used, and other factors. The friction coefficient significantly decreased when the wood moisture content was above the fiber saturation point.
