“…Nonetheless, as a key error, the angular offset ratio is necessary to be quantified. Based on the report of Yamamoto et al., 19 the diameter of shaft used in his study is 9 ± 0.0005 mm with 12 grooves formed in total. Therefore, the gap between each dimple in his study is not sufficient to ensure that the central line of each dimple exactly passes through the center point of the shaft during contact due to “global” oblateness of the cylinder created by roll forming deformation, which is illustrated in Figure 13.…”

“…For cylindrical parts, roll forming is more suitable than sheet rolling. Yamamoto and Kuwabara 19 have designed and built a micro form rolling machine to study the imprint ability of micro-grooves on the shaft. However, the forming mechanism applied in Yamamoto’s experiment is not strictly micro-forming.…”

Surface texture is one of the most promising methods to achieve friction reduction in the mechanical components, and it has been rapidly developed in the last decade. The friction reduction mechanism of regularly patterned surface texture is widely considered to be lubricant retention and debris entrapment. There are many ways to manufacture micro surface texture, among which deformed-based micro-surface texturing is the least studied. However, it has many unique advantages that cannot be surpassed by the rest, such as high production efficiency, fine geometrical fidelity and smooth surface finishing. Therefore, this study aims at developing a deformation-based low-cost micro form-rolling machine to create micro surface texture on the cylindrical component. A new demonstrator for examining the friction reduction efficiency of the micro surface texture has also been built and tested. Results show that the shaft with micro surface texture is able to reach a maximum of 48.1% friction reduction at rotation speed 400 r/min with lubricant SAE30 compared to the non-textured workpiece with the same condition.

This article discusses an overview of microforming, microcasting and microwelding processes. In the case of microforming, the processes reviewed are micro deep drawing, microforging, microextrusion, microrolling, microstamping, microhydroforming and incremental microforming. This section also throws some light on how the lasers have been used for microbending and micropunching purposes. The work done in the area of physics of microforming processes has also been discussed briefly. This article also deals with different types of microcasting processes particularly permanent mold and investment microcasting processes. The applications of these microcasting processes have been specified in different fields of engineering, biomedical and so on. Some areas in which further research work is needed have been identified. It includes both theoretical and experimental works which need attention. The last part of this article deals with microjoining in general and laser microjoining in particular. This section discusses the types of the lasers that are being used for microjoining purposes. The process parameters (laser, optics, system and material) have been explained, and some work done on the parametric analysis has been reported briefly. Various applications of laser microjoining have been elaborated before the last section on concluding remarks. This last section presents, in very brief, the areas in which further work is required in microjoining processes.

“…Little work has been done on metal as the rolling target. Only recently, work on metal was reported by Yamamoto et al [11] to fabricate microgrooves onto austenitic stainless steel (SUS303) and aluminum alloy (A5056) surfaces. However, the structure sizes were 10 μm in height and 0.5 mm in width.…”

The fabrication technique using the combination of nano plastic forming, coating and roller imprinting processes to transfer nano/micro patterns onto the surface of metallic materials is developed. In this process, nano plastic forming (NPF) of pure aluminum (Al 99%) using a diamond tool is combined with a coating technique to produce a nickel die. The nickel die is then used for the double plate roller imprinting process to transfer the pattern onto the surface of metallic material. Experimental works with 0.1 N to 1.0 N indentation load variations and 2.5 µm to 7.5 µm pitch variations using a knife edge diamond tool are conducted to study the feasibility of this technique. Comparisons between the master mold, nickel die and rolling result in terms of geometries show good agreement, thus validating the proposed approach for high throughput, low cost, low emission and flexible fabrication technique. The capability of the proposed method is demonstrated in the fabrication of cross, net and brick patterns.
