钢构件在热处理后通常必须进行机械加工，以获得正确的形状以及所需的表面光洁度。表面质量会影响诸如疲劳强度、磨损率、耐腐蚀性等特性。硬车削使制造商能够简化其工艺，同时仍能达到所需的表面光洁度质量。有各种参数，如切削速度、进给率和刀尖半径，已知它们对表面质量有很大影响。本文描述了进给率和刀尖半径如何影响车削中的表面完整性和疲劳寿命。结果表明，残余应力对疲劳寿命的影响比表面粗糙度的影响更为显著。这项工作的目的是确定34CrNiMo6的表面质量、车削工艺参数和疲劳行为之间的关系。(C) 2008爱思唯尔有限公司。保留所有权利。
Steel components often have to be machined after heat treatment in order to obtain the correct shape as well as the required surface finish. Surface quality influences characteristics such as fatigue strength, wear rate, corrosion resistance, etc. Hard turning allows manufacturers to simplify their processes and still achieve the desired surface finish quality. There are various parameters such as cutting speed, feed rate, and tool nose radius that are known to have a large impact on surface quality. This paper describes how feed rate and nose radius affect the surface integrity and fatigue life in turning. The results show that the effect of residual stress on fatigue life is more pronounced than the effect of surface roughness. The goal of this work is to identify a relationship between surface quality, turning process parameters and fatigue behavior of 34CrNiMo6. (C) 2008 Elsevier Ltd. All rights reserved.
