Sanding is a key process for the manufacture and application of medium density fiberboard (MDF). In this paper, the wear characteristics of abrasive belt and the impact on material removal were studied. The topological features which included surface roughness and height distribution were statistically analyzed. Specifically, interference ratio \(\varphi\) was introduced to evaluate the proportion of the actually involved grits, which was characterized by a significant correlation with the material removal. It was found that there were roughly three phases in the lifecycle of abrasive belt. Fracture and abrasion were the predominant wear patterns of the involved grits that was 68.6% on average. The grits dropping off the backing layer could be observed with 29.8%. Not involved grits accounted for roughly 31.4%. The grey relevancy analysis (GRA) indicated a morphology transfer phenomenon between the workpiece and the belt, while the surface roughness displayed a weak correlation with the material removal.

砂光是制造和应用中密度纤维板（MDF）的关键过程。本文研究了砂带的磨损特性及其对材料去除的影响。对包括表面粗糙度和高度分布在内的拓扑特征进行了统计分析。具体来说，干扰比\（\ varphi \）为了评估实际涉及的砂粒的比例，引入了这种方法，该方法的特点是与材料去除之间存在显着的相关性。发现砂带的生命周期大致分为三个阶段。断裂和磨损是所涉及砂粒的主要磨损形式，平均为68​​.6％。可以观察到29.8％的砂砾从衬里层脱落。不涉及的砂砾约占31.4％。灰色关联度分析（GRA）表明工件与皮带之间有形态转移现象，而表面粗糙度与材料去除之间的相关性较弱。
