Dry Milling Machining: Optimization of Cutting Parameters Affecting Surface Roughness of Aluminum 6061 using the Taguchi Method

Abstract

In this paper, the application of dry machining as part of contributions for development of a sustainable environment in the machining industry is explained. Achieving a good surface roughness product is one the most important factors that must be considered in the metal machining process. Surface quality control is a complicated process, and a reliable technique is required during machining operation. Currently, an appropriate cutting conditions in most of machining cases are determined by trial and error, which leads to time increased, energy consumption, and manufacturing costs. Most of the previous studies have investigated factors that affect surface roughness, but different machining conditions require the control of different factors. In this study, experiments were conducted to optimize cutting parameters and determine the factors significant for the surface roughness quality. Machining experiments were conducted on a vertical milling machine using square non-coated two flutes HSS Co end mill with selected cutting parameters on aluminum 6061. This study focused on the surface roughness in one direction and combined with the Taguchi design method. Signal-to-noise (S/N) ratio and analysis of variance (ANOVA) were employed to examine and reveal the factors that are significant in affecting surface roughness quality. The analysis result revealed that cutting speed exerts the highest effect on surface roughness, followed by feed rate and depth of cut. Finally, the combination of dry machining performance and an eco-friendly environment would result in competitive sustainable growth of the machining industry.

“…Metode Taguchi juga telah diaplikasikan dalam optimasi parameter proses gurdi yang mempengaruhi permukaan akhir dan akurasi dimensi (Aamir dkk., 2020). Banyak peneliti juga telah mengadopsi metode Taguchi untuk meneliti efek dari proses freis terhadap kekasaran permukaan yang optimal dan dimensi produk (Jenarthanan & Jeyapaul, 2013); (Ribeiro dkk., 2017); (Sulaiman et al, 2022). Penelitianpenelitian tersebut menunjukkan temuan yang memuaskan tentang cara menemukan kombinasi parameter proses yang ideal.…”

The Effect of Natural Fiber Percentage on the Tensile Strength of Paper Using ANOVA

“…We take a random sample from each population independently, size n1 from the first population, n2 from the second population, and so on, size nk from the k population. Sample data will be expressed with Yij, which means the jth data in the sample taken from the i-th population [17], [18], [19]. The one-way ANOVA test aims to compare more than two means.…”

Optimization of Machining Parameters on The Geometry Precision of Cortical Screw of Ti-6Al-4V ELI Using Gray Relational Analysis Method

“…As tool wear increases, the contact area between the tool and the workpiece increases, causing a greater cutting force. Therefore, to obtain product quality or high precision, it is necessary to optimize the machining process for titanium implant components [14].…”

“…In multi-response optimization, the influence of parameters is observed on several responses simultaneously. One method developed for the multi-response optimization process is Gray Relational Analysis (GRA) [14]. As stated by [15], the milling parameters for cutting tool wear and workpiece surface roughness were optimized using Taguchi and GRA methods.…”
