Abstract

This article examines the influence of cutting conditions on performance characteristics such as fatigue strength when milling with an end mill. Based on an analysis of the literature, it was found that fatigue strength depends on the quality of the surface layer of the part, the irregularities of which are stress concentrators. Based on the results of experimental studies, a mathematical model was obtained that describes the relationship between roughness and the stress concentration coefficient from the cutting conditions.

切削条件对产品操作特性的影响

摘要

本文研究了用立铣刀铣削时切削条件对疲劳强度等性能特征的影响。通过文献分析发现，疲劳强度取决于零件表面层的质量，表面层的不规则性是应力集中点。根据实验研究的结果，获得了描述粗糙度与切削条件下的应力集中系数之间关系的数学模型。
