Abstract

Quality machining on stainless steel AISI 304 is achieved by reducing the interface temperature generated due to high hardness and compressive frictional force. Temperature rise during the turning operation was observed to cause a weak tool nose, and machining surface. Enhanced lubricant properties can alleviate these issues and help reduce tool nose wear while increasing machined surface quality. Nano-lubricants have been prepared to meet the functional requirements for machining. Emulsifier oil-based nanofluids perform exceptionally well in heat transfer during machining. The present investigation focuses on copper oxide nanoparticles addition in “Society of Automotive Engineers 30” emulsifier oil at two different weight percentage: 1.5 wt.-% and 2.25 wt.-%, aiming to improve heat transfer and machined surface quality. In this experimental study, a computer numerical control machine tool, DCMT120404 insert, tool dynamometer, and infrared pyrometer are utilized for the machining operation. It was observed that 2.25 wt.-% copper oxide mixed emulsifier-nano cutting fluid exhibited minimum cutting force and work-tool interface temperature while enhancing the surface quality.

氧化铜纳米颗粒分散乳化剂切削液影响下 AISI 304 不锈钢的切削性研究

对 AISI 304 不锈钢进行高质量加工的方法是降低由于高硬度和压缩摩擦力而产生的界面温度。据观察，车削操作过程中的温度升高会导致刀头和加工表面变薄。增强润滑剂的性能可以缓解这些问题，有助于减少刀头磨损，同时提高加工表面质量。纳米润滑剂的制备满足了机加工的功能要求。乳化剂油基纳米流体在加工过程中的传热性能特别好。本研究的重点是在 "美国汽车工程师协会 30 "乳化剂油中添加两种不同重量百分比的氧化铜纳米粒子：1.5 wt.-%和 2.25 wt.-%，旨在改善热传递和加工表面质量。在这项实验研究中，使用了计算机数控机床、DCMT120404 刀片、刀具测力计和红外线高温计进行加工操作。结果表明，2.25 wt.-%的氧化铜混合乳化剂-纳米切削液在提高表面质量的同时，切削力和工件-刀具界面温度也最小。

期刊介绍： Materialwissenschaft und Werkstofftechnik provides fundamental and practical information for those concerned with materials development, manufacture, and testing. Both technical and economic aspects are taken into consideration in order to facilitate choice of the material that best suits the purpose at hand. Review articles summarize new developments and offer fresh insight into the various aspects of the discipline. Recent results regarding material selection, use and testing are described in original articles, which also deal with failure treatment and investigation. Abstracts of new publications from other journals as well as lectures presented at meetings and reports about forthcoming events round off the journal.
