Abstract

The main objective of this study is to initially simulate the cutting process of hardened AISI630 stainless steel to implement thermally enhanced turning followed by hot turning (HT) experiments to demonstrate the effectiveness of the process and identify cutting parameters that would yield the optimum results in terms of sustainability. To precisely predict the chip morphology, as well as the cutting force and tool temperature, 2 D and 3 D FEM analysis, have been used, respectively using AdvantEdge software. The numerical analysis showed that HT in 300 °C causes a reduction of 28% in cutting forces. The tool wear in HT reduces up to 33% in comparison to conventional turning (CT). Furthermore, the relation between cutting force fluctuation and the machined surface roughness has been investigated applying numerical analysis and experimental data. The results revealed that HT in 300 °C reduces the machined surface roughness up to 23%. In addition, it has been observed that HT technique decreases side flow and surface damages in comparison to CT.

摘要

本研究的主要目的是初步模拟硬化 AISI630 不锈钢的切削过程以实施热强化车削，然后进行热车削 (HT) 实验，以证明该过程的有效性并确定可产生最佳结果的切削参数的可持续性。为了精确预测切屑形态以及切削力和刀具温度，已分别使用 AdvantEdge 软件进行 2 D 和 3 D FEM 分析。数值分析表明，在 300 °C 下进行 HT 会使切削力降低 28%。与传统车削 (CT) 相比，HT 中的刀具磨损最多可减少 33%。此外，应用数值分析和实验数据研究了切削力波动与加工表面粗糙度之间的关系。结果表明，在 300 °C 下进行 HT 可将加工表面粗糙度降低 23%。此外，已经观察到与 CT 相比，HT 技术减少了侧流和表面损坏。
