Abstract:One of the lightest metallic materials used in the aeronautics, aerospace, and automotive industries, among others, is magnesium, due to its excellent weight/strength ratio. Most parts used in these industries need to be made of materials that are rigid, strong, and lightweight, but sometimes the materials do not simultaneously satisfy all of the properties required. An alternative is to combine two or more materials, giving rise to a hybrid component that can satisfy a wider range of properties. The pieces machined in these industrial fields must satisfy stringent surface roughness requirements that conform to the design specifications. This work shows an experimental study to analyse the surface roughness reached in hybrid components made up of a base of magnesium alloy (UNS M11917) and two inserts of aluminium alloy (UNS A92024) obtained by turning. Its purpose is to determine the influence of the factors and their possible interactions on the response variable, the surface roughness Ra. The study is carried out using a design of experiments (DOE). A product of a full factorial 2 3 and a block of two factors 3 × 2 was selected. The factors identified as possible sources of variation of the surface roughness are: depth of cut, feed rate, spindle speed, type of tool, location with respect to the specimen (LRS), and location with respect to the insert (LRI). Data were analysed by means of the analysis of variance (ANOVA) method. The main conclusion is the possibility to carry out the repair and maintenance of parts of magnesium-aluminum hybrid components by dry turning; that is, without cutting fluids and, therefore, in the most sustainable way that the process can be carried out. In addition, different combinations of cutting parameters have been identified that allow these operations to be carried out in an efficient manner, reducing mechanization times and, therefore, also the direct and indirect costs associated with them.

“…The roundness error is considered to be one of the important geometrical errors of cylindrical components because it has a negative effect on the accuracy and other important factors such as the mating mechanical components and wear of rotating elements. 5,6 The machine-tool rigidity and clamping system influence the form accuracy and dimensional tolerance in precision hard turning. Possible machining errors may be caused due to different types of clamping, the number of clamping jaws, clamping forces, the hydraulic pressure of a clamping system, the clamping rigidity and accuracy.…”

“…The results showed that the work material had the greatest effect on the diameter error and surface roughness, while the major contributor to the circularity was the blank size. Rafai and Islam 6 experimentally and analytically investigated the effects of the cutting parameters on the dimensional accuracy and surface finish in dry turning. The Taguchi method and the Pareto ANOVA analysis were used to determine the effects of the major controllable machining parameters and, subsequently, to find their optimum combination.…”

This paper is focused on optimizing the cutting conditions for the surface roughness, inner-diameter error and roundness obtained in hard turning of an inner ring bore. The hard-turning experiments were conducted on hardened and tempered AISI 52100 bearing rings using the L9 orthogonal array on a CNC lathe. The cutting speed, feed rate and number of the machined part were selected as control factors. The optimum cutting conditions were determined using the signal-to-noise (S/N) ratio. S/N ratios were calculated using the lower-the-better approach. An analysis of variance (ANOVA) was also employed to determine the level of the effect of the control factors for the surface roughness, inner-diameter error and roundness. The statistical analysis showed that the feed rate was the most significant factor for the surface roughness while the cutting speed was the most significant factor for the roundness and inner-diameter error. Finally, the optimum cutting conditions were further confirmed with confirmation tests. Keywords: diameter error, hard turning, roundness, surface roughness, Taguchi method lanek je osredinjen na optimiranje razmer pri rezanju glede na hrapavost povr{ine, napake notranjega premera in okroglosti pri trdem stru`enju notranjega roba izvrtine. Preizkusi trdega stru`enja so bili izvr{eni pri kaljenem in popu{~enem AISI 52100 obro~u le`aja z uporabo L9 ortogonalne matrike na CNC-stru`nici. Hitrost rezanja, hitrost podajanja in {tevilo obdelanih kosov so bili izbrani kot kontrolni faktorji. Optimalne razmere rezanja so bile izbrane z uporabo razmerja signal-hrup (S/N). S/N-razmerja so bila izra~unana s pribli`kom~im manj tem bolj{e. Analiza variance (ANOVA) je bila tudi uporabljena za dolo~itev vpliva kontrolnih faktorjev na hrapavost povr{ine, napak notranjega premera in okroglosti. Kon~no so bili optimalni parametri potrjeni s potrditvenimi preizkusi.

“…A typical approach has been to study the effects of major cutting parameters on dimensional accuracy parameters such as diameter error and circularity and surface finish parameters such as arithmetic average (R a ) and peak-to-valley height (R t ) for various materials, such as free machining steel (Davim, 2001), aluminium-copper alloy (Marcos-Bárcena et al, 2005), chromium alloy tool steel SKD11 (Tzeng et al, 2009), maraging steel (Lalwani et al, 2008), composite materials (Manna and Bhattacharyya, 2002), chrome molybdenum steel SCM 400 (Thamizhmanii et al, 2007), mild steel 1030 (Nalbant et al, 2007), and alloy steel 4340 (Rafai and Islam, 2009). However, most of these studies are based on a single work material and as a result do not provide any indication of the effect of different materials on the dimensional accuracy and surface finish of turned parts.…”

“…In recent years, a large number of studies have appeared in the literature to investigate the effects of cooling methods in turning operations with the aim of reducing the application of cutting fluids and their negative impact on the environment (Bruni et al, 2006;Dhar et al, 2006a;Dhar et al, 2007;Dilbag et al, 2006;Jayal and Balaji, 2009;Kamat and Obikawa, 2007;Klocke and Eisendlaetter, 1997;Lalwani et al, 2008;Marksberry and Jawahir, 2008;Pusavec et al, 2011;Rafai and Islam, 2009;Sharma and Dixit, 2007;Sreejith, 2008;Varadaarajan et al, 2002;Wakabayashi et al, 1997). Accordingly, non-traditional forms of turning, such as dry turning, turning with minimum quantity lubrication (MQL), and cryogenic turning, gained renewed emphasis.…”

& This article reports the experimental and analytical results of an investigation of additional factors that affect the dimensional accuracy and surface finish of turned parts besides the three major cutting parameters-cutting speed, feed rate, and depth of cut. The selected additional factors were cooling method, blank size, and work material. A three-level, three-parameter experiment was planned using design-of-experiment methodology. The three levels of independent input parameters were: for cooling method-dry turning, flood turning, and minimum quantity lubrication turning; for blank size-/20, 40, and 60 mm; and for work material-aluminium 6061, mild steel 1030, and alloy steel 4340. The measured output parameters were the two most widely used dimensional accuracy characteristics of turned parts-diameter error and circularity-and the surface finish characteristic arithmetic average. The results were analyzed applying three methods: traditional analysis, Pareto ANOVA, and Taguchi method. The results reveal that, while work material has the greatest effect on diameter error and surface roughness, the major contributor to circularity is blank size.
