Abstract

The problem of studying a scratch from a single abrasive grain is formulated, which involves finite element modeling of the interaction of the abrasive grain with the workpiece and an experimental study of obtaining and processing the grain traces on the real surface of the samples. A comprehensive investigation technique is proposed, including modeling the process of a single microcutting with an abrasive grain in the software system for analysis by the ANSYS Workbench finite element modeling method and an experimental study of the surface after microcutting with a grain. The applied research technique showed that, in general, the microreliefs of the traces created by a single abrasive grain, obtained during modeling and in the experiment, have a similar nature. At the same time, the numerical values of the geometric parameters have a scatter explained by a number of factors.

工件表面单个磨粒划痕的实验和有限元研究

摘要

提出了研究单个磨粒划痕的问题，其中涉及磨粒与工件相互作用的有限元建模以及在样品真实表面上获取和处理颗粒痕迹的实验研究。提出了一种综合研究技术，包括在软件系统中对磨粒单次微切削过程进行建模，并通过ANSYS Workbench有限元建模方法进行分析，并对磨粒微切削后的表面进行实验研究。应用研究技术表明，一般来说，在建模过程中和在实验中获得的由单个磨粒产生的痕迹的微浮雕具有相似的性质。同时，几何参数的数值存在由多种因素解释的分散性。
