The purpose of this research was an analysis of the optimum cutting conditions for the lowest surface roughness in tangential cylindrical grinding of the AISI D3 tool steel using the Taguchi method. In this experimental investigation, the surface roughness with various wheel speeds, workpiece speeds, feed rates and depths was observed. The surface roughness was investigated employing the Taguchi design of experiments and an analysis of variance (ANOVA). Significant machining parameters were identified using the signal-to-noise ratio. The results of the experiments indicate that the wheel speed and feed rate have dominating effects on the surface roughness during the cutting. The developed new grinding process can be used in the machining industries in order to determine the optimum cutting parameters for the minimum surface roughness.

Pri teh eksperimentih je bila opazovana hrapavost povr{ine pri razli~nih hitrostih kolesa, razli~nih hitrostih obdelovanca ter razli~nih hitrostih in globinah podajanja. Povr{inska hrapavost je bila preiskovana z uporabo Taguchi-jeve postavitve preizkusov in analize variance (ANOVA). Pomembni parametri obdelave so bili identificirani z uporabo razmerja signal -hrup. Rezultati eksperimentov ka`ejo, da imata hitrost kolesa in hitrost podajanja prevladujo~o vlogo pri hrapavosti povr{ine in parametrih rezanja. Razvoj novega postopka bru{enja se lahko uporabi v strojni industriji za dolo~anje optimalnih pogojev rezanja pri minimalni hrapavosti povr{ine. Klju~ne besede: tangencialno cilindri~no bru{enje, Taguchi metoda, hrapavost povr{ine, ANOVA
This study was carried out to improve the surface of the AA7075 alloy, which does not resist wear. Therefore Al–SiC composite layer on the surface of AA 7075 material was coated with Al+5vol.%SiC powders under 600∘C and 100, 120, 140[Formula: see text]MPa pressure by the hot pressing sintering method. The microstructure of the transition zone between the coating and the substrate material was analyzed by using optical microscopy (OM), energy dispersive X-ray spectroscopy (EDS), and scanning electron microscopy (SEM) techniques. In addition, XRD measurement and microhardness of the coating layer were obtained. Coating surface was also subject to linear reciprocating wear test and coefficient of friction (COF), wear volume, and mass loss were detected. The results have shown that micro-pores between Al and SiC powders reduced by increasing the pressing pressure. However, although there was a reduction in wear volume and mass loss, microhardness values dramatically increased. Wear test was modeled in ANSYS 2021 R2 package program depending on Archard’s law and numerical analysis was conducted. As a result of the experimental results and numerical analysis, the volume loss values occurring in the coating area were found to be compatible with each other.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
