摘要

Fe-Ni合金具有优异的耐热性能，同时在高温下保持其刚性、强度、韧性和尺寸稳定性。因此，它们被广泛用于制造工作温度非常接近其熔化温度的航空航天或航空部件。Supra50(在统一编号系统UNS中命名为K94800)是目前在航天航空工业中使用的铁镍合金，其效率得到了证实。然而，提高这种高精度零件的表面粗糙度是制造过程中难以克服的难题。本研究的主要目的是进行基于析因计划的实验，旨在预测Supra50零件的表面粗糙度作为铣削过程中切削参数的函数。结果表明，当每齿进给量最小时，切削参数的最佳组合能获得最佳的表面粗糙度。结果还表明，切削速度和径向深度对粗糙度质量影响不大。

Experimental optimization of cutting conditions to improve surface roughness of aeronautic parts made of Fe-Ni alloys

Fe-Ni alloys present excellent heat resistance properties while preserving their rigidity, strength, toughness, and dimensional stability at high temperatures. As a result, they are widely used in manufacturing aerospace or aeronautic parts where the operating temperature is very close to their melting temperature. Supra50 (named in the Unified Numbering System UNS as K94800) is a Fe-Ni alloy currently used in space and aviation industries, which confirmed its efficiency. However, improving the surface roughness of this high-precision part is challenging to overcome in manufacturing. The main objective of this study is to carry out an experiment based on a factorial plan and aims to predict the surface roughness of Supra50 parts as a function of cutting parameters in a milling process. Results show that the best combination of cutting parameters, giving the best surface roughness, is obtained at the lowest value of feed per tooth. Results also show that cutting speed and radial depth have little effect on roughness quality.

期刊介绍： Manufacturing industries throughout the world are changing very rapidly. New concepts and methods are being developed and exploited to enable efficient and effective manufacturing. Existing manufacturing processes are being improved to meet the requirements of lean and agile manufacturing. The aim of the Journal of Engineering Manufacture is to provide a focus for these developments in engineering manufacture by publishing original papers and review papers covering technological and scientific research, developments and management implementation in manufacturing. This journal is also peer reviewed. Contributions are welcomed in the broad areas of manufacturing processes, manufacturing technology and factory automation, digital manufacturing, design and manufacturing systems including management relevant to engineering manufacture. Of particular interest at the present time would be papers concerned with digital manufacturing, metrology enabled manufacturing, smart factory, additive manufacturing and composites as well as specialist manufacturing fields like nanotechnology, sustainable & clean manufacturing and bio-manufacturing. Articles may be Research Papers, Reviews, Technical Notes, or Short Communications.
