“…Based on the shapes, these ranges were within the values obtained by Dali et al (2016), Chen et al (2018a), Greco et al (2009) and Kurniawan and Ko (2013), which are an excellent range of values in dimple texturing for tribology. Table 5 shows the results for the geometries of the dimples fabricated from the experiment in Table 2.…”

“…Area ratio for these two experiments was acceptable because of being within the suggested range (10%-20%) as mentioned earlier in Table 6. The dimple shape and dimension (length, width and depth) for Experiments 7 and 8 were within the range of the shape and dimension produced by Dali et al (2016), Chen et al (2018a), Greco et al (2009) and Kurniawan and Ko (2013). Nevertheless, the arrays were not uniform and inconsistent.…”

“…In machining, surface texture can be produced through various processes, such as electrochemical machining, turning, milling, micro-ultrasonic machining, micro drilling machining, abrasive jet machining and reciprocating fast-tool-feeding (Uehara et al , 2004; Chen et al , 2018a; Mahata and Bhattacharyya, 2020). These processes have been previously used by other researchers in obtaining better solutions in terms of types of surface texture, methods used, exact ranges of surface texture sizes and suitable shapes for surface textures.…”

Purpose This research aims to present the characteristics of dimple structure which was fabricated using a turning machine, where the characteristics include sizes, shapes, area ratio and aspect ratio. This research aims at filling the gap in the machining parameters of previous research in producing dimple by using turning process with the aid of dynamic assisted tooling for turning (DATT). In producing dimple, a carbide insert grade H1 was used on a hypereutectic aluminium silicon alloy (A390) material. Dimple has many advantages such as for reducing friction coefficient, load-carrying capacity and trap wear debris for sliding mechanical components. Design/methodology/approach There are seven machining parameters (cutting speed, feed rate, depth of cut, frequency, amplitude, rake angle, relief angle and nose radius) which have an influence on dimple produced. Taguchi method (orthogonal arrays L8) was used to conduct the experiment systematically and efficiently for these seven parameters. A carbide insert grade H1 was used as a cutting tool on a turning machine with the aid of DATT. The dimple structure was fabricated on a cylindrical rod hypereutectic aluminium silicon alloy (A390). A profilometer 3D Alicona infinite focus and an optical microscope equipped with Vis software were used to analyse the fabricated dimple structure. Findings Various shapes and sizes of ellipse dimples were produced in this research, including short and long drops with lengths in the range of 517.03–3,927.61 µm, widths of 565.15–1,039.19 µm, depths of 14.46–124.87 µm, area ratios of 5.05–25.65% and aspect ratios of 0.007%–0.111%. There were four experiments within the optimal area ratio range of 10%–20%, i.e. the second, third, seventh and eighth experiments. The width of these dimples was 895.95, 961.39, 787.27 and 829.22 µm, length was 826.26, 3163.13, 885.98 and 1026.65 µm, depth was 83.67, 84.19, 87.05 and 110.70 µm and area ratio was 15.12%, 13.14%, 14.79% and 12.70%. The surface roughness of textured surface was below 1 µm. In this research, the results obtained were similar with that of previous researchers on dimple structure related to tribology performance. Originality/value There exists machining parameters, namely, cutting speed and frequency, that were not used by previous research in producing dimple. These machining parameters (cutting speed and frequency) were used in this research to produce dimple via turning process with the aid of DATT using carbide insert grade H1. The turning process is an environmentally friendly process which is suitable for mass production for fabricating dimple structure as compared to most of the current methods which are widely used in fabricating dimple structure.

“…The device operates in resonant mode with tangential and normal vibration almost as same as the resonant frequency. Chen et al [88] developed a reciprocating fast tool feeding mechanism using an elliptical cam drive for the rapid fabrication of micro-texture arrays on the surface. The elliptical cam operates as the drive mechanism for the reciprocating feed tool system.…”

This paper presents a brief review of surface texturing with a focus on piston assembly application. The paper begins with a general discussion on surface texturing and the manufacturing process of micro dimples. Further, it discusses the theory of hydrodynamic lift generation and the effect of parameters of micro dimples texture on the surface-to-surface friction. Finally, the effect of surface texturing on heat transfer is briefly discussed. In pursuits to improve internal combustion engine (ICE) efficiency, tribological improvement of moving surfaces by means of micro surface texturing seems to be one of the way. However, texturing parameters have to be carefully designed as it can cause detrimental effect if the designs are wrong. Studies has shown micro surface texturing at piston ring could reduce friction around 20%-50% compare with un-textured piston ring and also reduce fuel consumption at 4%. Micro Surface texturing could also improve heat transfer between the surfaces to reduce piston slap and lubrication oil temperature. As reports on the surface texturing on friction reduction and heat transfer improvement in piston assembly are relatively scarce, it is suggested that optimization of micro dimple parameters for piston skirt application and its effect on engine tribology and heat transfer characteristics to be further investigated.
